Reducing Autonomous Vehicle Accidents: What Is Actually Working<\/h4>\n\n\n\n
Despite the legal and ethical complexity, the safety record of mature autonomous vehicle systems is improving. Waymo published a peer-reviewed study in 2024 showing that its vehicles were involved in significantly fewer injury-causing crashes per mile than human-driven vehicles in comparable environments. The key advances driving this improvement include higher-resolution sensor fusion combining LiDAR, radar, and cameras with redundant processing; improved simulation training using synthetic edge-case scenarios that would be dangerous or impossible to stage in reality; and V2X (vehicle-to-everything) communication, which allows vehicles to share real-time information about hazards, traffic conditions, and each other’s positions.<\/p>\n\n\n\n
Regulators are also improving the frameworks around incident reporting and investigation.

Autonomous vehicle accidents liability remains one of the most unresolved legal questions in modern technology law.

Sally Knew the Road. But Who Was Responsible? In 1953, Isaac Asimov published a short story called “Sally” in Fantastic magazine. In it, self-driving cars with positronic brains roam a farm for retired automobiles, developing personalities and emotional responses. When a villainous character attempts to exploit them, Sally and the other cars act to protect themselves and the humans they care for. Asimov, as he so often did, had seen something clearly: that autonomous vehicles capable of independent action would inevitably raise questions that went far beyond engineering. Questions about agency, intention, and most pressingly, responsibility. Seventy years later, those questions are no longer philosophical. They are legal, regulatory, and deeply urgent. Autonomous vehicle accidents liability has become one of the most contested areas in technology law, as self-driving cars move from test tracks to public roads and courts, insurance companies, and legislators scramble to answer the question Asimov posed in fiction: when an autonomous vehicle causes harm, who is accountable? The Scale of the Problem Autonomous vehicles are no longer experimental. Waymo, the autonomous driving subsidiary of Alphabet, completed over four million fully driverless trips in 2024 and is currently expanding into new cities including Miami and Tokyo. Tesla’s Full Self-Driving system is active on hundreds of thousands of vehicles on public roads. In 2025, the US National Highway Traffic Safety Administration (NHTSA) reported receiving over 2,500 incident reports involving vehicles with automated driving features, a figure that represents only a fraction of actual incidents due to inconsistent reporting requirements. The accidents are real and, in some cases, fatal. In 2023, a Cruise autonomous vehicle in San Francisco struck a pedestrian who had already been hit by another car, then dragged her 20 feet before stopping. California’s Department of Motor Vehicles revoked Cruise’s operating licence. General Motors ultimately shut down the Cruise unit. In 2024, a Waymo robotaxi in Phoenix struck a cyclist who had run a red light. The cyclist was injured but survived. Both incidents raised the same fundamental question that courts and regulators have yet to answer cleanly: who is responsible for autonomous vehicle accidents when the vehicle itself made the decision? The Legal Framework in the United States Under current US law, autonomous vehicle accidents liability falls into a patchwork of state-level frameworks with no coherent federal standard. This is partly because US traffic law has historically been a state matter, and partly because Congress has repeatedly failed to pass comprehensive autonomous vehicle legislation, most recently when the SELF DRIVE Act stalled in 2021. In practice, autonomous vehicle accidents liability in the US currently resolves through three legal theories. The first is product liability: the argument that the autonomous vehicle system was defective and the manufacturer is responsible, in the same way that a tyre manufacturer is liable for a blowout caused by a manufacturing defect. The second is negligence, directed either at the manufacturer for deploying an inadequately tested system, or at the human operator, if one was present, for failing to intervene. The third is agency liability, an emerging theory that treats the vehicle’s AI as acting on behalf of its manufacturer, making the manufacturer responsible for the AI’s decisions the way an employer is responsible for an employee’s actions in the course of their work. Most autonomous vehicle accident lawsuits in the US have settled before reaching verdict, which has slowed the development of clear case law. Arizona, California, and Texas have enacted their own autonomous vehicle frameworks, but these differ significantly on questions including whether a human must be present in the vehicle, what data must be retained after an incident, and who must report accidents and to whom. The NHTSA’s Standing General Order, introduced in 2021 and strengthened in 2023, now requires manufacturers to report all crashes involving automated driving systems within one day if an airbag deployed or a fatality occurred. This has dramatically improved data collection but has not resolved the underlying autonomous vehicle accidents liability question. The European Approach: Stricter, Clearer, but Still Evolving The European Union has taken a more structured approach to autonomous vehicle accidents liability. The EU’s updated Product Liability Directive, which came into force in December 2024, explicitly covers AI systems and software as “products,” meaning that manufacturers of autonomous vehicle systems can be held liable for damages caused by defects in their AI, including defects that arise from inadequate training data, flawed algorithms, or failure to update the system against known risks. Germany moved first among EU member states, passing the Autonomous Driving Act in 2021, which created a legal framework for Level 4 autonomous vehicles (those capable of driving themselves in defined conditions without human intervention) and established that when an autonomous vehicle accidents liability question arises, the vehicle owner’s compulsory insurance covers damages, with the right to pursue the manufacturer if a technical defect is found.
