Federal Rules Are Coming for Self-Driving Cars

US safety regulators convene Waymo, Zoox, and Aurora to reshape AV safety standards as commercial scaling begins

30 Mar 2026

The hardest part of any technology transition is deciding when the experiment ends and the rules begin. For autonomous vehicles in America, that moment may have arrived.

On March 10th the National Highway Traffic Safety Administration (NHTSA) gathered the chief executives of Waymo, Zoox, and Aurora in Washington for a full-day forum on self-driving safety. The signal was deliberate: robotaxis and driverless freight trucks are no longer prototypes. They move through American cities and along interstate corridors every day, and the regulatory framework has not kept pace.

NHTSA administrator Jonathan Morrison led a fireside discussion with Waymo's co-chief executive Tekedra Mawakana, Zoox chief Aicha Evans, and Aurora founder Chris Urmson. Their companies are at different stages of a shared challenge: translating technically impressive pilot programmes into something resembling a national industry. Waymo has accumulated 200 million fully autonomous miles and provides hundreds of thousands of weekly rides across several American cities. Aurora is running driverless freight between Houston and Dallas. Zoox has deployed a purpose-built urban vehicle with no steering wheel, no pedals, and no fallback driver.

Two substantive debates shaped the forum. The first concerned how safety should be measured. Relying on crash statistics alone, several panellists argued, is inadequate: accidents are rare by design, and waiting for them to reveal problems is an unreliable method of oversight. Leading behavioural indicators, including safety-margin violations and data from unusual edge cases, were proposed as more informative tools. The second debate addressed remote assistance, a feature that allows human operators to intervene when vehicles encounter unexpected situations. Network latency, cybersecurity exposure, and the risk of operator overload all drew scrutiny. Incidents in which remote systems were overwhelmed during large-scale urban disruptions, panellists noted, are already informing redesigns.

The stakes of the regulatory exercise are not trivial. NHTSA confirmed it is drafting its first updated official guidance on automated driving systems since 2017, a document written before commercial robotaxi service existed. A public comment period runs until April 10th.

For operators with strong safety records, tighter standards are not necessarily a constraint. They are a competitive advantage. The harder question is whether the rules, once written, will be rigorous enough to mean something.
