US Cities and States Tighten Autonomous Vehicle Rules Amid Federal Deadlock

America’s self-driving car industry is facing a growing tangle of local rules as cities and states step in where Congress has failed to act. With national autonomous vehicle legislation stalled in Washington for several years, local authorities are using their existing powers over street permits, fleet operations and transport management to impose their own conditions on robotaxi services.

The situation was reported by technology news outlet The Verge, which described the resulting regulatory environment as exactly the kind of fragmented, city-by-city mess that autonomous vehicle companies had spent years lobbying to prevent.

Congress Sits on Its Hands

The United States has no agreed national framework governing how autonomous vehicles are deployed commercially. That gap has left individual cities and states to work out the rules for themselves — and they’re doing it in very different ways.

Local authorities don’t control how vehicles are built. That sits with federal regulators. But they do control how vehicles operate on their roads, and that’s the lever they’re pulling.

The Verge notes that the stalemate in Congress has persisted for several years, with proposed legislation repeatedly failing to clear both chambers. In the meantime, robotaxi services have expanded into more US cities, and public pressure on local politicians to act has grown.

What Minneapolis and San Diego Are Doing

Two cities illustrate the range of approaches being considered.

Minneapolis is weighing an ordinance that would require a human monitor inside any autonomous vehicle operating in the city. If passed, that rule would effectively end fully driverless operations — the core commercial model for companies like Waymo and its rivals. The final legal status of the Minneapolis proposal has not been confirmed from available sources.

San Diego has moved further. The San Diego City Council has passed a resolution seeking to block Waymo vehicles from serving the city’s airport. The resolution also aims to give local agencies direct control over autonomous vehicles during emergencies. Again, whether that resolution carries enforceable legal weight remains unverified.

But the direction of travel is clear. Cities want a say.

A Patchwork Nobody Wanted

Proposed US legislation — at both city and state level — includes measures that would allow local authorities to cap the size of autonomous vehicle fleets, restrict operating hours, and impose outright permit bans in certain areas.

For companies operating across multiple cities, that creates a compliance headache. A robotaxi that runs legally in one city may fall foul of rules the moment it crosses into a neighbouring jurisdiction. The Verge characterised this as precisely the fragmented regulatory landscape that industry leaders had sought to avoid by pushing for a single national standard.

And it’s not just a commercial problem. Different rules between neighbouring areas raise genuine questions about accountability — who is responsible when something goes wrong, and under which rulebook?

Who’s Pushing Back, and Why

The moves don’t appear to fall neatly along political lines. The Verge’s reporting suggests that concerns about autonomous vehicle oversight span jurisdictions across the US political spectrum. That makes a quick federal fix even harder to engineer — there’s no obvious coalition to push a single bill through Congress.

From the industry’s point of view, a national framework would at least offer consistency. From a city’s point of view, handing control to Washington means giving up the ability to respond to local conditions — road layouts, population density, public transport gaps, emergency service needs.

Neither side is entirely wrong. That’s what makes this hard.

The UK Picture

The United States dispute does not directly affect UK roads. Britain has its own legislative process, and autonomous vehicle regulation here sits with Westminster rather than with local councils — though local transport authorities and highways bodies do have a role in how roads are managed day to day.

For their part, the UK’s Automated Vehicles Act 2024 received Royal Assent last year, giving Britain a national legal framework for self-driving vehicles ahead of most other countries. That puts the UK in a different position to the US, where the absence of equivalent federal legislation is precisely what has triggered the local scramble.

What This Means for Kent Residents

Kent residents won’t feel any direct effect from American cities’ disputes with robotaxi operators — UK roads run under British law, not US municipal ordinances. But the broader lesson from the US experience is relevant: as autonomous vehicle services edge closer to UK deployment, the shape of national legislation will matter enormously to how and where those services operate. If self-driving vehicles or robotaxi services were ever proposed for Kent — whether for public transport, NHS patient transport, or community services — it would be Kent County Council, Medway Council and local highways authorities working within that UK national framework, not writing their own rules from scratch.
