1. Introduction

The automotive sector is swiftly progressing towards a future characterized by autonomous vehicles (AVs), with driverless cars at the forefront of this evolution. The vehicles utilize state-of-the-art technologies, such as intricate sensor networks, advanced artificial intelligence (AI), and real-time data processing, which together hold the potential to transform transportation by improving safety, efficiency, and convenience. Nonetheless, the incorporation of these complex systems brings forth significant cybersecurity is- sues that need to be tackled to safeguard AV performance and guarantee user safety.

Historically, autonomous vehicle research has spanned several decades, marking the transition of AVs from speculative fiction to a reality on our roads today. Experiments in this field began as early as the 1920s with Ralph Teetor’s invention of cruise control, and later expanded into semi-autonomous systems developed by Japan’s Tsukuba Mechanical Engineering Laboratory in the 1970s. These early projects laid the foundation for subsequent advancements, including Carnegie Mellon University’s Navlab and ALV projects, which achieved milestones in autonomous cross-country travel by the mid-1990s [1, 2, 3]. Government support, such as the United States’ $650 million allocation for the National Automated Highway System in the 1990s [4], further bolstered AV innovation, eventually enabling private industry players like Waymo, Tesla, and Nuro to lead commercial deployments from the late 2010s onward [5, 6].

In recent years, the concept of AVs has rapidly advanced due to technological progress, transitioning from controlled test environments to limited public road usage. Notably, McKinsey’s 2023 global executive survey highlights significant advancements, with insights from 86 decision-makers forecasting the commercial availability of Level 4 (L4) autonomous vehicles and robotaxis by 2030. Despite these advancements, substantial financial investments remain necessary. For instance, developing fully autonomous trucks and L4/L5 robotaxis requires over $4 billion and $5 billion, respectively [7]. This ongoing progress underscores the industry’s commitment but also highlights the resource- intensive nature of AV development.

This study uniquely contributes to the AV landscape by conducting a comparative analysis between AVs and drones. This comparison is particularly valuable because drones have encountered a wide array of cybersecurity threats. By examining these threats, the research explores how similar vulnerabilities could manifest within AV systems, thereby offering a basis for understanding potential misuse of AV technology. This insight allows for proactive mitigation strategies that can be applied to both AVs and drones, enhancing our overall preparedness against cyber threats.

However, the adoption of AVs at scale faces numerous hurdles, including regulatory, safety, and cybersecurity concerns. The cybersecurity landscape is especially complex, with threats such as remote exploits, unauthorized access, and adversarial machine learning attacks posing significant risks to AV systems [8]. The increasing reliance on wireless communication in AVs exposes them to attacks that could compromise vehicle control, sensitive data, and communication networks. The rapid evolution of cybersecurity risks between 2023 and 2024, such as adversarial attacks against AI systems and supply chain vulnerabilities, further emphasizes the need for robust cybersecurity protocols.

Beyond cybersecurity, AVs must also navigate regulatory and societal challenges. As the industry grows—projected to reach $556.67 billion by 2026—collaboration among auto- motive sectors, regulatory bodies, and researchers becomes essential to address the socioeconomic impacts, such as job displacement within driving-related industries. Trust- building initiatives, such as Waymo’s extensive road testing and Tesla’s Full Self-Driving (FSD) program, continue to play a critical role in driving public acceptance [6, 9, 10].

Through this study, readers will gain insights into AV technologies, the associated cybersecurity risks, and the broader societal and regulatory challenges. By presenting a detailed comparative analysis with drones, this research not only identifies shared vulnerabilities but also provides a framework for preemptive mitigation strategies. This exploration is intended to equip readers with a holistic understanding of AV technology, guiding them through the steps needed for safe, efficient, and socially responsible autonomous transportation. The projected growth trends [11] for the autonomous vehicle market are illustrated in Figure 1.

2. Motivation

There are a number of powerful incentives that are driving the development of autonomous vehicles. Each of these incentives addresses significant societal, economic, and environmental challenges respectively:

2.1. Enhancing Road Safety

An important driving force behind the development of autonomous vehicles is the ability to improve road safety by greatly reducing human error, which is a major contributor to traffic accidents. As per the World Health Organization, some 1.3 million individuals perish annually in road traffic accidents, with the bulk of these incidents being caused by human error [12, 13]. Driverless cars utilize sophisticated sensors, machine learning algorithms, and real-time data processing to enhance decision-making capabilities, sur- passing those of human drivers. This results in a decreased probability of accidents and a significant preservation of human life [14].

2.2. Increasing Transportation Efficiency

Through the optimization of vehicle movement and the reduction of the amount of time spent driving, autonomous vehicles have the potential to change the efficiency of transportation. It is possible for autonomous vehicles to establish contact with one another as well as with traffic management systems. This allows them to coordinate their movements, limit the number of occasions in which they are forced to stop and go, and determine the routes that are ultimately the most efficient. It is possible that these outcomes will result in greater traffic efficiency, decreased traffic congestion, and shorter travel durations [15, 16]. These outcomes are beneficial to individual commuters as well as the economy as a whole because they will increase productivity and decrease fuel consumption simultaneously [17, 18].

2.3. Reducing Traffic Congestion

Traffic congestion has a substantial impact on urban areas, leading to inefficiency in terms of time management, increased levels of pollution, and economic setbacks. Through the synchronization of their movements, the optimization of the timing of traffic lights, and the reduction of the need for parking spots in densely populated metropolitan areas, autonomous cars have the potential to alleviate traffic congestion. The integration of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication gives autonomous cars the capacity to dynamically adjust their speed and routes in order to avoid traffic congestion and maintain a continuous movement of vehicles. Such a feature allows autonomous vehicles to maintain a consistent movement of vehicles [19, 20, 21].

2.4. Improving Mobility for All

Autonomous vehicles have the potential to significantly improve the transportation alternatives available to individuals who are unable to operate a vehicle, such as the elderly, the disabled, or those who do not have their own means of transportation [22]. Individuals who may have difficulties with mobility can benefit from the on-demand transportation services provided by autonomous vehicles, which offer a reliable and convenient mode of transportation. This has the potential to improve self-sufficiency, facilitate access to essential services, and eventually lead to an improvement in the overall quality of life for the aforementioned demographics [23].

2.5. Contributing to Environmental Sustainability

The optimization of driving patterns, the decrease of idle time, and the encouragement of the use of electric vehicles (EVs) are all ways in which autonomous vehicles have the potential to improve environmental sustainability. Because they are able to operate more efficiently and eliminate excessive acceleration and braking, driverless cars have the potential to reduce the amount of fuel that is consumed as well as the emissions of greenhouse gases [24]. A large and infrastructure. Table 1 provides a brief overview of these technologies, highlighting the essential components used in each.

2.6. Economic Benefits

There is a high probability that the introduction of autonomous vehicles will result in considerable economic benefits. It is possible to realize significant cost savings in the areas of healthcare, emergency services, and vehicle repairs by reducing the number of accidents that occur on the roads. A large reduction in the number of accidents that occur in the United Kingdom, for instance, might result in savings of almost two billion pounds by the year 2030 at the very least [27]. Furthermore, it is predicted that the autonomous automobile industry will provide a multiplicity of employment opportunities in the areas of technological innovation, infrastructure advancements, and mobility services. This sector would also deliver more than £51 billion in economic benefits [28].

2.7. Accessibility and Inclusion

Autonomous vehicles have the potential to provide individuals with disabilities, the elderly, and other individuals who do not drive with enhanced mobility options, thereby boosting their freedom and general well-being [22]. Autonomous cars have the potential to be designed in such a way that they can accommodate a wide range of accessibility requirements, thereby offering a reliable and safe mode of transportation to all users.

3. Technologies Behind Driverless Cars

The technology used in driverless automobiles is varied and intricate, encompassing the integration of advanced sensors, artificial intelligence, vehicle-to-vehicle and vehicle-to- infrastructure communication, and sophisticated decision- making algorithms. These technologies collectively allow autonomous vehicles to accurately detect their surroundings, precisely determine their location, strategize safe routes, and efficiently navigate while interacting with other vehicles and infrastructure. Table 1 provides a brief overview of these technologies, highlighting the essential components used in each.

Table 1: An Overview of Technologies

3.1. Sensors and Perception Systems

The powerful sensors and vision systems used in autonomous vehicles are central to their operational capabilities. These systems combine various types of sensors to collect and interpret data from the surrounding environment, generating a comprehensive view. LiDAR (Light Detection and Ranging) systems emit laser pulses, measuring the time it takes for them to reflect off objects, which helps create high-resolution 3D maps [29]. This is crucial for identifying the shape, distance, and size of obstacles, enabling precise environmental mapping and navigation. Radar sensors, which use radio waves to detect the distance and speed of objects, are essential for adaptive cruise control and collision avoidance, and are particularly effective in adverse weather where optical sensors may fail [30]. Visual cameras capture images of the environment that are processed using computer vision algorithms for tasks such as object recognition, lane detection, and traffic sign identification. Modern autonomous vehicles typically deploy multiple cameras to cover various angles, creating a complete visual representation of the surroundings. Ultrasonic sensors [31], primarily used for short-range detection, assist in parking maneuvers by detecting objects close to the vehicle, ensuring safety during low-speed operations. Collectively, these perception systems synthesize data from multiple sources to produce an accurate model of the vehicle’s surroundings, which is fundamental for decision-making and control activities.

3.2. Localization and Mapping

Accurate localization and mapping are essential for autonomous vehicle navigation, as they enable vehicles to determine their precise position and navigate complex environments. The Global Positioning System (GPS) provides basic positioning information, but in urban settings, where signal blockages by tall buildings can occur, GPS is often supplemented by other localization technologies. Inertial Measurement Units (IMUs) track the vehicle’s orientation and motion, supplying critical data for dead-reckoning and enhancing GPS accuracy. Simultaneous Localization and Mapping (SLAM) is another key technology, involving algorithms that build a map of the environment while simultaneously tracking the vehicle’s position within it. SLAM integrates data from LiDAR, cameras, and IMUs to produce detailed and accurate maps, which are vital for navigating dynamic and unfamiliar surroundings. Advanced navigation systems often employ a hybrid approach, combining fundamental maps with real-time perception data to adapt to immediate environmental changes [32]. Innovations from institutions like MIT’s CSAIL have even developed systems that rely on sparse topological maps and real-time sensor data, allowing autonomous vehicles to navigate without detailed maps.

3.3. Decision-Making Algorithms

Autonomous vehicles rely on sophisticated decision- making algorithms to interpret sensor data and execute driving tasks safely and effectively. Path planning algorithms determine the optimal route from the vehicle’s cur- rent position to its destination, using techniques such as graph-based search (e.g., A* algorithm) and optimization methods to ensure collision-free paths. These algorithms also dynamically adjust to real-time traffic conditions and obstacles [33]. Obstacle avoidance algorithms detect and navigate around obstacles with inputs from LiDAR, radar, and cameras, utilizing methods like Detection and Tracking of Moving Objects (DATMO) to forecast obstacle movements and adjust the vehicle’s path accordingly [33]. Additionally, predictive modeling anticipates the actions of other road users, such as pedestrians or other vehicles, by applying machine learning models, including deep neural networks, to enhance the accuracy of these predictions. Together, these decision-making processes enable the vehicle’s control system to analyze the environment, adhere to traffic rules, and ensure secure and efficient movement.

3.4. Vehicle-to-Vehicle (V2V) Communication

Vehicle-to-Vehicle (V2V) communication enables autonomous cars to share real-time information on their speed, position, and driving intentions. This exchange of data improves situational awareness and facilitates coordinated maneuvers, such as platooning, where vehicles travel in close formations to reduce aerodynamic drag and enhance fuel efficiency. V2V communication ensures precise coordination of speed and braking among platooned vehicles, which bolsters both safety and efficiency. Furthermore, V2V is crucial for accident prevention, as it allows vehicles to relay alerts about potential hazards, sudden stops, or other critical incidents [34].

3.5. Vehicle-to-Infrastructure (V2I) Communication

Vehicle-to-Infrastructure (V2I) communication involves interactions between vehicles and road infrastructure, such as traffic lights, road signs, and other smart systems. This technology plays a key role in optimizing traffic flow, as vehicles can receive real-time updates on traffic conditions, signal timings, and available detours, thereby reducing congestion and improving travel times. V2I communication also enhances road safety by providing vehicles with warnings about hazards, construction zones, or changes in road conditions. Integration with smart city infrastructure further extends V2I’s capabilities, enabling comprehensive traffic control and significant improvements in urban transportation [34].

3.6. Artificial Intelligence and Machine Learning

Artificial Intelligence (AI) and Machine Learning (ML) are critical components of the architectures that enable autonomous driving. These technologies empower vehicles to learn from data, recognize patterns, and make decisions in complex situations. Deep Learning, for instance, is used extensively for visual perception, object recognition, and decision-making. Through deep neural networks, autonomous vehicles can process inputs from various sensors to detect objects, recognize traffic signs, and predict the actions of other road users. Reinforcement Learning, on the other hand, allows vehicles to learn from real-world driving experiences and continually enhance their performance. This adaptive approach enables autonomous systems to refine their decision-making processes over time and respond effectively to new environments. Overall, AI systems in autonomous vehicles facilitate the interpretation of sensory data, enable situational awareness, and support safe navigation without human intervention, improving their capabilities as they encounter diverse driving conditions.

4. Levels of Autonomy

4.1. SAE Levels of Automation

The Society of Automotive Engineers (SAE) has defined six levels of vehicle automation, from Level 0 (no automation) to Level 5 (full automation), which describe the degree of driver intervention required and the vehicle’s capabilities at each stage [35]. These levels provide a framework to understand the evolution and technical capabilities of AV systems:

1. Level 0 (No Automation): At this level, the human driver is fully responsible for controlling the vehicle. While some technologies, such as warnings or momentary assistance (e.g., collision alerts), may be present, they do not control the vehicle.
2. Level 1 (Driver Assistance): Basic driver-assist technologies, such as adaptive cruise control or lane- keeping assistance, enable limited control over either steering or acceleration/deceleration, but not simultaneously. Current technologies at this level often employ sensors and basic AI to interpret lane markings or maintain a safe following distance.
3. Level 2 (Partial Automation): The vehicle can control both steering and speed under certain conditions, using a combination of radar, LiDAR, and camera systems to monitor the environment. Although the driver remains responsible for monitoring the road and staying alert, this level marks the transition to shared control.
4. Level 3 (Conditional Automation): Vehicles at this level can manage all driving tasks under specific conditions, such as highway However, the driver must be ready to take over when the system requests. The transition between automated and manual control relies on advanced sensor fusion and environmental mapping, allowing the system to make decisions based on real-time data processing.
5. Level 4 (High Automation): At this stage, the vehicle can perform all driving functions and monitor the environment in designated operational design domains (ODDs), such as urban areas or specific weather conditions, without driver intervention. While human oversight is not needed within the ODD, technological limitations prevent full autonomy under all conditions, with industry leaders like Waymo and Cruise currently testing Level 4 systems in pilot.
6. Level 5 (Full Automation): This level represents the goal of fully autonomous vehicles, capable of per- forming all driving tasks in all conditions without any human intervention. The technical challenges include creating a robust infrastructure of AI, machine learning, and V2X communication, but full industry adoption remains unrealized as of 2024.

Industry Adoption and Comparison: While significant strides have been made in Levels 2 and 3, full Level 5 automation is not yet achieved. Currently, automakers and tech firms, such as Tesla and Waymo, are focusing on improving Levels 3 and 4 with varied strategies. Tesla’s approach, for example, relies heavily on computer vision and advanced neural networks for higher levels of autonomy, while Waymo incorporates high-definition mapping and extensive LiDAR systems. The comparative analysis within this paper explores these strategies, emphasizing how different companies prioritize elements like sensor fusion and machine learning to overcome the unique challenges at each automation level. By highlighting these approaches, the paper outlines key industry practices that contribute to the broader landscape of AV technology development [35].

4.2. Gradual Progression Towards Full Autonomy

The transition towards complete autonomy is slow, with cars now functioning at either Level 2 or Level 3. These levels enable vehicles to do specific driving tasks while still necessitating human supervision. The transition to higher levels of automation will be driven by notable progress in technology and legal frameworks. For instance, the testing and implementation of Level 3 systems such as Honda’s “Traffic Jam Pilot” and Mercedes-Benz’s Drive Pilot demonstrate encouraging advancements in minimizing human intervention in particular situations.

Autonomous vehicles must address various challenges before achieving full autonomy, including:

• Advanced Software and Mapping: Ensuring the software can handle diverse driving conditions and environment.s.
• Human Factors: Developing systems that can safely transfer control between human drivers and autonomous systems.
• Regulatory and Legal Frameworks: Establishing standards for liability, safety, and operation of autonomous vehicles.
• Ethical and Security Concerns: Addressing ethical dilemmas such as the “trolley problem” and ensuring robust cybersecurity measures.

The continued research and development efforts that are being made by industry leaders, government agencies, and academic institutions are absolutely necessary in order to overcome these hurdles and make progress toward completely autonomous vehicles.

Complex Urban Environments: This is a challenge for autonomous vehicles because of the unpredictability and complexity of urban environments. The use of autonomous vehicles (AV) presents considerable issues in situations where there is a high volume of traffic, pedestrians, cyclists, and emergency vehicles.

Adverse Weather Conditions: The reliability of autonomous vehicles (AV) systems can be negatively impacted by weather conditions such as rain, snow, and fog, which can hinder the functioning of sensors like as cameras and LiDAR. The creation of reliable systems that are capable of functioning successfully in any and all weather circumstances continues to be a significant problem.

Cybersecurity: When it comes to protecting autonomous vehicles (AVs) against hacking and data breaches, it is necessary to provide comprehensive cybersecurity safeguards. Because of the high level of connectivity that exists amongst autonomous vehicles, any vulnerabilities that may exist could be exploited, which could result in the theft of important data or the malicious control of the vehicle.

Regulatory and Ethical Issues: A thorough regulatory framework must be developed in order to facilitate the broad use of autonomous vehicles (AVs). The establishment of standards for safety, liability, and insurance is included in this requirement. In addition, it is necessary to handle ethical conundrums, such as the process of making decisions in situations where accidents are unavoidable.

To summarize, although there have been notable progressions, it is imperative to do further research and development in order to surmount these obstacles and fully realize the capabilities of autonomous cars.

6. Existing Cybersecurity Threats

Driverless cars are equipped with a multitude of interconnected systems that manage everything from navigation to communication with external devices. These systems are susceptible to various types of cyberattacks, including:

6.1. Remote Exploits and Unauthorized Access

The dependence on wireless connectivity renders autonomous vehicles susceptible to remote exploitation. Unauthorised gain of access to the vehicle’s control systems by attackers has the potential to result in catastrophic failures. As an illustration, in 2015, security researchers Charlie Miller and Chris Valasek successfully conducted a remote hack on a Jeep Cherokee by taking advantage of weaknesses in its Uconnect smart entertainment system. Unauthorized access to the vehicle’s internal network was successfully obtained, enabling the delivery of commands to vital systems such as the engine, gearbox, and brakes. The cyber assault demonstrated that vehicles with unsecured connectivity might be influenced from any location, therefore giving rise to significant apprehensions regarding the security of autonomous vehicles [36].

6.2. Data Breaches and Privacy Concerns

Autonomous vehicles amass huge quantities of data, encompassing personal information as well as driving trends. Data breaches have the potential to result in the unauthorised acquisition and improper use of this confidential data. The 2016 Uber data breach, which compromised the personal data of 57 million passengers and drivers, highlights the possible hazards linked to the extensive data retention inherent in autonomous vehicles. Uber’s former Chief Security Officer, Joe Sullivan, endeavored to conceal the breach by offering the hackers $100,000 as part of a “bug bounty” scheme, resulting in severe legal repercussions [37].

6.3. Vehicle-to-Everything (V2X) Communication Attacks

Driverless cars communicate with infrastructure, other vehicles, and even pedestrians through Vehicle-to- Everything (V2X) technology. These communications are critical for safe operation but are vulnerable to various types of attacks.

In 2019, researchers demonstrated the feasibility of spoofing GPS signals to mislead autonomous vehicles, potentially causing them to veer off course or crash. This attack involves transmitting fake GPS signals that override the vehicle’s legitimate signals, leading to dangerous miscalculations [38].

V2X communication also relies on wireless signals that can be jammed, disrupting the flow of crucial information. In 2021, a jamming attack was demonstrated where multiple vehicles were rendered unable to receive or send data, causing significant traffic disruptions and even roadblocks. These incidents highlight the vulnerabilities in V2X communication protocols that could be exploited to create gridlock or force vehicles into unsafe conditions [39].

Additionally, relay attacks have been used to intercept and delay V2X messages, causing vehicles to react to out dated or incorrect information. This can lead to dangerous situations where vehicles may fail to stop at red lights or collide due to delayed braking signals [40].

6.4. Sensor Spoofing Attacks

Vehicle perception systems, including LiDAR, radar, and cameras, are vulnerable to sensor spoofing. Attackers have the ability to create deceptive signals that can be mistaken for genuine objects by these sensors. As an illustration, studies have shown that by projecting certain patterns onto road signs, the vehicle’s image recognition system can be tricked into misinterpreting the sign, which could result in risky decisions. In a similar vein, through the use of laser spoofing, malicious individuals have the ability to manipulate LiDAR readings. This can result in the creation of deceptive obstacles or the concealment of genuine ones [41].

6.5. Malware and Software Exploits

Vehicle software can be targeted by malware attacks that take advantage of weaknesses in the operating system or third-party applications. As an example, in 2018, a group of experts made an important finding regarding a vulnerability in Tesla’s Model S. This finding enabled them to remotely control the vehicle. The attack was carried out by taking advantage of a vulnerability in the vehicle’s browser, which enabled the researchers to insert harmful code. Once inside, they had the ability to control various aspects of the car, including unlocking doors and even steering [42].

6.6. Man-in-the-Middle (MitM) Attacks

Intercepting and potentially altering communications between the vehicle and external systems is a common occurrence in MitM attacks. In 2020, a groundbreaking discovery was made when experts successfully showcased a method of intercepting V2X communication, resulting in a potential vulnerability for Tesla vehicles. The manipulation of sensor data led to the vehicle misinterpreting its surroundings. Such an attack has the potential to result in the vehicle receiving inaccurate information, such as incorrect speed limits or traffic signals, which can lead to unsafe driving behavior [43].

6.7. Denial-of-Service (DoS) Attacks

Denial of Service (DoS) attacks aim to incapacitate a vehicle’s systems or communication channels by inundating them with excessive traffic. In a recent experiment con- ducted in 2019, a group of researchers successfully demonstrated a disruptive attack on a fleet of autonomous vehicles. The attack involved overwhelming the vehicles’ communication channels with an excessive amount of traffic, causing them to experience a denial-of-service (DoS) situation. This incident resulted in a total disruption of vehicle-to-vehicle (V2V) communication, resulting in a breakdown of synchronized driving and the possibility of accidents [44].

7. Emerging Threats in 2023-2024

Recent advancements in AI and machine learning have introduced new dimensions to cybersecurity threats in driverless cars. The following are some of the most concerning threats identified in the past year:

7.1. Adversarial Machine Learning (AML) Attacks

As driverless cars increasingly rely on AI to make real- time decisions, they become targets for adversarial machine learning (AML) attacks. These attacks exploit vulnerabilities in AI models by introducing carefully crafted perturbations to the input data. These perturbations, often imperceptible to human observers, can cause the AI to make incorrect decisions, such as misclassifying road signs or obstacles. For instance, in 2023, researchers demonstrated that by placing inconspicuous stickers on stop signs, they could cause AI systems in driverless cars to misinterpret them as yield signs, leading to potentially dangerous outcomes. The technical complexity of AML attacks lies in the ability to generate perturbations that evade detection while consistently fooling the model across various scenarios, making them a significant threat to the safety and reliability of autonomous vehicles [45].

7.2. Supply Chain Attacks

The global supply chain for automotive components is vast and interconnected, making it a prime target for sophisticated cyberattacks. In 2024, a major automotive supplier was compromised through a multi-stage attack that involved the insertion of malware into firmware up- dates for critical components used in driverless cars. The malware was designed to remain dormant, undetected by traditional security measures, until specific conditions were met, at which point it would activate and allow remote attackers to take control of the affected vehicles. This attack exemplifies the growing complexity and reach of supply chain threats, where the integrity of software and hardware components can be compromised at any point along the supply chain, from manufacturing to distribution. The challenge in defending against these attacks lies in the need for comprehensive verification processes and the integration of secure development practices across all tiers of the supply chain [46].

7.3. Ransomware Targeting Vehicle Systems

Ransomware targeting AI-driven and autonomous vehicles represents an emerging cybersecurity challenge due to the complexity and connectivity of these systems. Such attacks could exploit vulnerabilities in the vehicle’s software stack, potentially locking down critical systems like navigation, braking, or powertrain control. By encrypting the vehicle’s control systems, ransomware [47] can render the car inoperable until a ransom is paid, usually in cryptocurrency. The decentralized nature of these attacks makes them difficult to trace, and the integration of AI increases the risk, as machine learning models can be manipulated or disrupted to exacerbate the impact. Additionally, the connected ecosystem of vehicles, with constant communication to cloud services and other devices, introduces multiple attack vectors, such as over-the-air updates, that can be compromised. This highlights the urgent need for multi-layered security strategies, including robust encryption, anomaly detection systems, and secure software development practices to mitigate these risks [48].

7.4. Keyless Car Theft and Relay Attacks

The advent of key less entry and ignition systems in modern vehicles has introduced new security vulnerabilities in the automotive industry. These conveniences have become targets for sophisticated theft techniques, particularly man-in-the-middle attacks. Such attacks exploit the communication between cars and key fobs, allowing thieves to unlock and start vehicles without triggering alarms [49]. In 2023, the discovery of Bluetooth relay attacks on Tesla vehicles highlighted another critical weakness. This exploit took advantage of vulnerabilities in Bluetooth Low Energy (BLE) protocols used in passive entry systems. By relaying Bluetooth signals, attackers could access vehicles without the physical presence of the key fob. Although Tesla addressed this specific issue with a software update, the incident underscored a broader cybersecurity challenge [50].

7.5. Risks in Autonomous Vehicle Charging Infrastructure

As electric vehicles (EVs) have evolved, cybersecurity vulnerabilities in their charging infrastructure have become a significant concern. These issues are even more critical for autonomous vehicles (AVs), which also rely on secure data exchange with charging stations. The increased complexity and autonomy of AVs heighten the risks, including the potential for malware, fraud, remote manipulation, and disabling of charging stations. These vulnerabilities pose serious threats to the safety and integrity of the autonomous vehicle ecosystem [51].

7.6. Causing Traffic Jams

The interconnected nature of autonomous vehicles makes them vulnerable to coordinated cyberattacks that could lead to significant traffic disruptions. By compromising the control systems of multiple driverless cars simultaneously, an attacker could create artificial traffic jams. For instance, cars could be programmed to slow down or stop in strategic locations, blocking key intersections or highways [52]. Such disruptions could be used as a form of protest, to create chaos in urban environments, or as a precursor to other criminal activities, such as facilitating the escape of criminals from law enforcement by creating diversions.

7.7. Noise Pollution

In recent events, San Francisco residents experienced disturbances due to Waymo’s autonomous vehicles persistently honking in residential areas during nighttime hours. This unexpected behavior, initially captured on video by local residents, drew significant public attention and prompted Waymo to respond with an apology and immediate corrective measures. According to Waymo, the honking feature was originally designed to minimize collision risks on public roads by signaling to other vehicles and pedestrians. However, when applied in confined parking areas, the feature led to excessive noise pollution, particularly during early morning hours, causing distress to the community [53]. This incident not only highlights the complexities and unintended consequences of deploying autonomous vehicles in urban environments but also raises concerns about potential misuse. Autonomous vehicles’ honking functions could be exploited by cybercriminals to create targeted noise pollution in densely populated areas. If an AV system were to be compromised, attackers could manipulate honking or other sound features, intensifying urban noise pollution and causing widespread disruption. This example underscores the need for robust cybersecurity measures that address not only operational functionality but also safeguard against potential abuses that could impact public well-being. As AV technology continues to advance, these considerations will be crucial for ensuring harmonious integration within urban settings.

8. Countermeasures for AV Cybersecurity Threats

Autonomous vehicles (AVs) encounter various cybersecurity threats that can jeopardize their safety, operational capabilities, and the confidence of the public. This section examines essential strategies aimed at reducing these risks through the improvement of AV system security against a range of potential attacks.

Surveys indicate that safety concerns are at the core of this reluctance. For example, in 2024, AAA reported that about 66% of Americans harbor fears about fully autonomous vehicles due to incidents and perceived risks associated with these systems [66].

Additionally, a World Economic Forum report underscores the role of clear communication and regulatory transparency in enhancing public trust in AV technology. The report emphasizes that as people become more familiar with AV safety measures and technological advancements, their confidence is likely to grow, thereby facilitating a smoother transition to autonomous transportation systems [67]. Understanding and addressing these consumer concerns is crucial for real-world implementation, as public acceptance directly impacts adoption rates and can guide regulatory approaches to foster trust in AV technologies.

9.3. Automated Vehicle Accident Statistics

The safety of self-driving cars is a subject that sparks heated discussions, especially as the technology progresses. In 2022, automakers disclosed around 400 crashes to the National Highway Traffic Safety Administration (NHTSA) involving vehicles equipped with partially automated driver- assist systems. Out of all the incidents, 273 of them involved Tesla vehicles, and interestingly, 70% of these Teslas were using the Autopilot beta feature at the time. It is worth mentioning that 11 of the crashes reported led to severe injuries, while five of them tragically resulted in fatalities. Meanwhile, in 130 reported accidents involving fully autonomous vehicles, there were no injuries in 108 cases, with the majority of incidents being rear-end collisions [65].

9.4. Liability in Autonomous Vehicle Accidents

Assessing responsibility in accidents involving autonomous vehicles introduces an additional level of intricacy to conventional traffic incidents. When a self-driving car is involved in an accident, it becomes essential to determine if the automated driving system was active during the collision and the level of human driver intervention that was anticipated. If there is a suspicion of a flaw in the AV’s system, the incident might be subject to product liability law [68]. In such cases, it is necessary to provide evidence of the defect and establish a clear link between the defect and the resulting injury.

9.5. Market and Technological Advancements

The autonomous vehicle industry is making significant strides, with continuous advancements in levels of vehicle automation. Various systems currently exist, with different levels of assistance provided to drivers. At the lowest level, drivers receive only momentary assistance, while at the highest level, the vehicle is capable of handling all driving tasks in any condition. Driver-assist technologies have be- come a common feature in the majority of new cars. These technologies encompass a range of helpful features such as automatic emergency braking, lane-keeping assistance, and adaptive cruise control [69]. As companies like Mercedes- Benz receive approval to deploy these technologies, more advanced systems, such as Level 3 automation, are becoming increasingly prevalent. These systems allow vehicles to manage most driving tasks independently.

10. Comparative Analysis: Drones vs. Driverless Cars

Technological breakthroughs in autonomous systems have propelled drones and autonomous vehicles to the forefront of contemporary innovation, providing unparalleled advantages in transportation, logistics, and surveillance. Nevertheless, the autonomy that fuels these advantages also brings about substantial cybersecurity vulnerabilities, which give rise to concerns over their possible abuse.

Drones [70] and autonomous vehicles have common technological underpinnings, such as the utilization of GPS for navigation, sensors for environmental perception, and artificial intelligence (AI) for decision-making operations. Both technologies are highly dependent on real-time data processing and external connectivity, rendering them vulnerable to cyber attacks such GPS spoofing, jamming, and unauthorized data interception.

Nevertheless, their operational environments vary greatly. Drones function within airspace and are commonly employed for the purposes of surveillance, delivery, and reconnaissance, rendering them susceptible to abuse in illicit activities such as smuggling, covert surveillance, or even as weaponry [70]. Conversely, autonomous vehicles skillfully maneuver through intricate metropolitan landscapes, prioritizing transit and logistics, where the vulnerabilities to hacks encompass hijacking, remote control, and the potential for accidents. Understanding these potential threats is crucial for developing appropriate countermeasures.

Given these distinct yet overlapping vulnerabilities, it is essential to explore the specific ways in which both drones and AVs can be exploited by cybercriminals. The following subsections delve into these potential threats, comparing how they manifest in drones and AVs.

10.1. Tracking and Surveillance

Driverless cars can be misused as tools for tracking and surveillance. Since these vehicles are equipped with GPS, cameras, and other sensors, a compromised car can be used to monitor an individual’s movements without their knowledge. Cybercriminals or other malicious entities could hijack the car’s systems to gather real-time data about the location and activities of the occupants, effectively turning the vehicle into a surveillance tool. While drones are also susceptible to being used for surveillance, their typical use in airspace makes them less likely to be involved in long- term tracking within dense urban environments, where AVs are more commonly found. This kind of misuse raises significant privacy concerns, especially if sensitive personal information is intercepted or recorded.

10.2. Transporting Illegal Items

Driverless cars could be exploited for the unauthorized transportation of illegal goods, such as drugs, weapons, or contraband. Since these vehicles operate autonomously, they could be programmed to follow predetermined routes to specific drop-off locations, reducing the need for human involvement and lowering the risk of detection.

Drones, too, are vulnerable to such misuse, particularly for smuggling goods across borders or into restricted areas. However, the ground-based nature of AVs means they are more likely to be used for covert operations within urban areas. This capability could be particularly appealing to criminal organizations looking to minimize the risks associated with traditional methods of smuggling and transportation.

10.3. Weaponization and Terrorism

In the worst-case scenarios, driverless cars could be weaponized by cybercriminals or terrorists. By hijacking a vehicle’s control systems, an attacker could direct the car to drive into a crowded area or a critical piece of infrastructure, such as a bridge or a building. The vehicle could also be loaded with explosives or hazardous materials, turning it into a remote-controlled bomb. While drones have similarly been considered for such malicious purposes due to their aerial capabilities, the ground-based nature of autonomous vehicles allows them to carry larger payloads and target densely populated urban environments more effectively. The potential for such attacks highlights the importance of securing the software and communication systems of autonomous vehicles to prevent their use in acts of terrorism.

10.4. Coordinated Cyberattacks

Driverless cars, like drones, are part of a broader network of interconnected systems, including other vehicles, traffic management systems, and cloud-based services. This inter- connectivity increases the risk of coordinated cyberattacks [71], where multiple vehicles are compromised and used in concert to achieve a malicious goal. Such attacks could disrupt urban infrastructure, create widespread panic, or even be used as a tool for cyber warfare. The ability to remotely control large numbers of autonomous vehicles presents a unique challenge to cybersecurity professionals, who must develop strategies to detect and neutralize such threats before they can cause harm. For instance, the Ukrainian government has developed advanced drone systems capable of coordinated attacks [72]. These drones can intercommunicate, autonomously decide on targets, and collect intelligence at speeds surpassing human capabilities. This development illustrates the potential for autonomous systems to be used in coordinated actions, highlighting the need for robust cybersecurity measures in both military and civilian autonomous vehicle networks.
