The fight over driverless cars: regulation, safety, and the future

01The regulatory battle in cities and states

A self-driving car, also known as an autonomous car or driverless car, is a vehicle capable of operating with reduced or no human input. In the United States, the authority to operate these vehicles on public roads is primarily delegated to states, creating a fragmented regulatory landscape. California, Arizona, Nevada, and Texas have been the most permissive, allowing driverless testing and commercial robotaxi operations. San Francisco has become ground zero for the regulatory battle, with the city repeatedly challenging Waymo and Cruise expansion permits before the California Public Utilities Commission.

The tension between state-level permitting and local governance is a core structural problem. State regulators approve robotaxi operations, but city governments bear the consequences — blocked intersections, emergency vehicle interference, and public complaints. San Francisco city officials filed formal objections to the CPUC, citing 631 documented incidents of Cruise and Waymo vehicles malfunctioning in ways that disrupted traffic and emergency response between 2022 and 2023.

Other cities have taken more cautious approaches. New York City requires a permit for autonomous vehicle testing, with stringent safety requirements. Austin, Texas, has welcomed Waymo but faced pushback from neighborhood groups. The patchwork means that autonomous vehicle companies must navigate a different regulatory regime in each jurisdiction, creating both compliance costs and strategic opportunities to forum-shop for favorable regulatory environments.

02Safety incidents and public perception

Safety incidents have shaped public perception more than any technical achievement. In October 2023, a Cruise autonomous vehicle struck and dragged a pedestrian in San Francisco, leading the California DMV to suspend Cruise's driverless deployment permits. The incident exposed gaps in the robot's ability to respond to unusual collision scenarios and prompted a broader reassessment of safety reporting requirements.

NHTSA's Standing General Order on crash reporting requires manufacturers of automated driving systems to report crashes. The data reveals hundreds of incidents involving Tesla Autopilot, Waymo, and Cruise vehicles, though the circumstances and severity vary widely. The most common incident types involve vehicles stopping unexpectedly in traffic, blocking intersections, and failing to yield to emergency vehicles.

Public opinion has turned more negative as incidents accumulate. A 2024 AAA survey found that 66% of Americans are afraid of fully self-driving vehicles, up from 55% in 2022. Only 9% of respondents said they would trust riding in a driverless car, a figure that has declined year over year. The chart below illustrates the depth of public skepticism.

03Labor unions and the taxi industry response

Labor unions have emerged as one of the most organized opposition forces against driverless vehicles. The Teamsters and the Transport Workers Union have lobbied state legislatures to restrict autonomous vehicle deployment, arguing that robotaxis eliminate jobs for professional drivers. In California, unions backed legislation that would have required a human safety operator in autonomous vehicles, though the bill was vetoed.

The taxi and ride-hailing industry has also mobilized. Traditional taxi medallion owners, whose investments have already been devastated by Uber and Lyft, see driverless fleets as an existential threat. Some taxi companies have pivoted to partnering with autonomous vehicle operators, offering their dispatch infrastructure and brand in exchange for operating the vehicles. Others have lobbied for regulations that would level the playing field, including requiring robotaxis to obtain taxi permits and comply with the same insurance and safety requirements.

The economic argument for unions is straightforward: approximately 3.8 million Americans work as drivers — truck drivers, taxi drivers, delivery drivers, and ride-hailing operators. Even partial automation of these jobs would affect more workers than any previous technological displacement. The counterargument from the autonomous vehicle industry is that new jobs in fleet management, remote operation, and maintenance will offset losses, though the transition period remains the critical challenge.

04Insurance and liability in the autonomous era

The insurance industry is grappling with a fundamental question: when a driverless car crashes, who pays? Traditional auto insurance is built around driver liability — the assumption that a human driver is responsible for the vehicle's operation. When the vehicle operates autonomously, liability shifts toward the manufacturer, the software developer, and the fleet operator.

Mercedes-Benz made a significant precedent by assuming liability when its Level 3 Drive Pilot system is engaged. This means the automaker, not the driver, is responsible for crashes that occur during autonomous operation. Volvo made a similar commitment for its Level 4 ambitions. But no universal standard exists, and Level 2 systems like Tesla's FSD explicitly place liability on the human driver, even though the system is performing the driving.

Insurance companies are developing new products for the autonomous era. Fleet insurance policies that cover robotaxi operators are emerging, with premiums based on autonomous miles driven and safety performance data. But the actuarial models for autonomous driving are still in their infancy, with limited data on long-term crash rates and severity. The industry is watching the first major liability case involving a fully autonomous vehicle to see how courts allocate responsibility.

05Urban planning and infrastructure changes

Driverless cars require changes to urban infrastructure that go beyond the vehicles themselves. Dedicated lanes, smart traffic signals that communicate with autonomous vehicles, and geofenced pickup and dropoff zones are all under discussion. Transportation planning, the process of defining future policies, goals, and investments to prepare for future mobility needs, must now account for the possibility that vehicles will operate without human drivers.

Some cities have begun adapting. Phoenix has installed dedicated curbside zones for robotaxi pickups. San Francisco has debated restricting autonomous vehicle access to certain neighborhoods during peak hours. The question of whether autonomous vehicles reduce or increase traffic congestion remains contested: while efficient routing could reduce congestion, empty robotaxis circulating between fares could increase vehicle miles traveled.

Parking infrastructure faces a particular transformation. If robotaxis drop passengers and drive to the next fare or return to a central depot, demand for urban parking could decline dramatically, freeing valuable city real estate for other uses. Some urban planners envision a future where parking lots and garages are repurposed for housing, parks, or commercial space. This vision remains speculative, but the infrastructure implications of driverless cars extend deep into urban design.

06The equity question: who benefits?

The equity dimensions of autonomous vehicle deployment are often overlooked but increasingly central to the policy debate. Robotaxi services initially launch in affluent, well-mapped urban areas where demand is highest and operating conditions are favorable. Low-income neighborhoods, rural areas, and communities with poor road infrastructure are likely to be served last, if at all. This mirrors the digital divide in broadband access and raises similar concerns about access to transportation as a basic necessity.

Proponents argue that autonomous vehicles could eventually improve mobility for underserved populations. Elderly and disabled individuals who cannot drive would gain access to on-demand transportation. Communities underserved by existing taxi and ride-hailing services could benefit from robotaxi networks that do not discriminate based on destination. The American with Disabilities Act has been invoked in arguments both for and against autonomous vehicles: they could improve accessibility, but only if deployed equitably.

The labor equity dimension is equally important. Driverless technology disproportionately affects workers in lower-income jobs — taxi drivers, delivery workers, and truck drivers. These workers are less likely to have savings, transferable skills, or access to retraining programs. The communities most dependent on driving jobs are often the same communities underserved by current transportation options, creating a double bind: losing employment while waiting for autonomous mobility benefits.

07The legislative landscape across countries

The global regulatory landscape for autonomous vehicles is diverging. The United Kingdom passed the Automated Vehicles Act in 2024, establishing a comprehensive legal framework for self-driving cars that includes liability allocation, safety standards, and deployment rules. Germany approved Mercedes' Level 3 system under its national framework, and the European Union is developing continent-wide regulations for autonomous driving through its AI Act and vehicle safety directives.

China has taken the most aggressive approach to deployment. Baidu's Apollo Go operates driverless robotaxi services in Wuhan, Beijing, Shenzhen, and other cities, with fewer regulatory constraints than Western counterparts. The Chinese government has designated entire zones for autonomous vehicle testing and has invested in the infrastructure — smart traffic signals, 5G connectivity, and HD mapping — that autonomous systems require. This regulatory permissiveness has given Chinese companies a testing advantage.

In the United States, the absence of federal autonomous vehicle legislation remains a significant barrier. The SELF DRIVE Act passed the House of Representatives but stalled in the Senate. NHTSA has issued standing orders and guidance, but without comprehensive federal legislation, companies operate under a patchwork of state laws. The question of whether the U.S. will establish a national framework for autonomous vehicles — or continue to let states and cities lead — remains one of the most consequential unanswered policy questions in the transportation sector.
