US robotaxi boom meets a wall of state and local regulation
As Waymo, Zoox, and Tesla expand their autonomous fleets, a fragmented patchwork of state and local rules is emerging, forcing operators to navigate conflicting demands from regulators, unions, and federal agencies.
The rapid expansion of robotaxi services across the United States is colliding with a growing tide of regulatory scrutiny and labour opposition. While major operators such as Waymo, Zoox, and Tesla continue to deploy autonomous vehicles, state and local governments are moving to impose stricter controls. These measures include new permitting requirements, vehicle caps, and fees, creating a complex legal landscape that industry leaders argue has not kept pace with the technology’s deployment.
In New York, Governor Kathy Hochul withdrew a proposal to allow driverless robotaxis outside New York City following strong opposition from taxi drivers, unions, and state lawmakers. Consequently, commercial driverless service remains illegal in the state, with legalisation efforts currently stalled. In Washington, DC, lawmakers are weighing legislation that includes a 200-vehicle cap and a 15-cent-per-mile fee designed to fund Metro upgrades and support displaced workers. This debate followed a grueling 10-hour City Council hearing, highlighting the intensity of local political friction.
San Francisco presents a different dynamic, where Mayor Daniel Lurie, previously a vocal supporter of the technology, is now calling for tougher regulations. This shift follows incidents where Waymo vehicles caused traffic disruptions during emergencies and major events. Meanwhile, California police gained the authority in July to formally cite autonomous-vehicle manufacturers when their driverless cars break traffic laws. At the federal level, the National Highway Traffic Safety Administration (NHTSA) has warned that autonomous vehicles unable to safely interact with first responders pose a public danger.
Despite the regulatory headwinds, the market leaders continue to scale operations. Waymo, the current market leader, operates more than 3,500 vehicles in 11 US cities and has been cleared by the California Public Utilities Commission to expand driverless service across parts of 18 counties. Zoox has begun offering paid rides in Las Vegas and continues free trips in San Francisco, with plans to extend its Explorer program to Austin and Miami later this year. Tesla is growing its unsupervised fleet ahead of launching its purpose-built robotaxi, the Cybercab, later this month.
Labour unions are increasingly framing the issue as an economic battle rather than just a safety concern. Peter Finn, international vice president at large for the Teamsters, described autonomous vehicles as an “existential threat” to workers, including truckers and delivery drivers. The union is pushing for legislation requiring a trained human operator aboard heavy-duty autonomous vehicles, a measure that has been vetoed twice by California Governor Gavin Newsom. Finn argued that if the technology is solely designed to automate and eliminate labour costs, the primary beneficiaries are corporations.
Industry leaders generally support clearer federal standards but resist restrictive local limits. Zoox CEO Aicha Evans stated that the company agrees with the need for regulation, while Waymo’s global head of public policy, Justin Kintz, argued for a balanced approach where the federal government sets vehicle safety standards, states govern road rules, and cities handle local concerns. The Autonomous Vehicle Industry Association notes that only about half of US states have passed laws allowing vehicles to operate without humans, underscoring the need for a more unified legal framework.
