San Francisco Mayor Daniel Lurie wants binding Waymo robotaxi regulations after a July 4 fireworks crowd turned a sizeable stretch of the city into a hours-long car park. Nearly two weeks after dozens of Waymo vehicles ran out of power, stalled in heavy traffic, and blocked key streets near the Presidio, Lurie has written to California’s State Transportation Agency demanding that the state establish enforceable, statewide standards for autonomous vehicles operating during major events.
The letter, first reported by the San Francisco Chronicle, singles out two incidents: a widespread power outage in December and the Golden Gate Bridge fireworks show on 4 July, which drew 100,000 spectators. In both cases, dozens of Waymo vehicles became immobile, compounding gridlock that trapped municipal shuttles and left thousands of people stranded.
The situation on 4 July was, by any measure, chaotic. The SF Standard reported that San Francisco’s emergency management chief described it as ‘havoc on the streets.’ ABC7 News reported that one Waymo vehicle carrying passengers was seen driving over a lit firework in the Presidio area, and that some vehicles required towing. No injuries were reported.
The Case for Waymo Robotaxi Regulations
Lurie’s letter spells out four ‘core operational capabilities’ he wants companies to demonstrate before regulators. Under his proposed framework, autonomous vehicle operators would need to immediately remove or relocate stalled robotaxis from active travel lanes, adapt routes and service areas in real time, share live operations data with local agencies, and pass testing that proves their fleets can handle large influxes of people and traffic.
Lurie acknowledged that Waymo had, in advance of the evening, agreed to restrict its service near the waterfront and had assigned a representative to the city’s emergency operations centre. It was not enough. Vehicles ended up stranded well outside the restricted zone, partly because the closure of the Golden Gate Bridge pushed crowds and traffic into surrounding streets that the pre-agreed boundaries did not cover.
An expert observer quoted by KRON4 put his finger on a specific technical gap: ‘One of the things that’s surprisingly clear in the whole situation on the Fourth of July is that you have multiple cars from Waymo and they are not connected to each other.’ Individual vehicles, in other words, were making decisions without awareness of what the rest of the fleet was doing, which made coordinated recovery impossible.
Lurie’s position has shifted from booster to enforcer. In the letter he wrote that the incidents ‘demonstrated that California’s current regulatory framework does not adequately address how autonomous vehicles operate during major incidents, planned or not,’ and that voluntary agreements are no longer sufficient given the scale Waymo has reached. He added that the four proposed requirements ‘will not undermine autonomous vehicles; they will strengthen them.’
Federal Scrutiny Arrives at the Same Moment
Lurie is not alone in pressing for action. On 8 July, the National Highway Traffic Safety Administration wrote to major autonomous vehicle companies saying it had noticed ‘a clear pattern of driverless AVs interfering with law enforcement and other first responders,’ and called on all operators to ‘immediately focus their resources on fixing this issue.’
Waymo, for its part, offered a measured response. A spokesperson told KRON4: ‘We appreciate Mayor Lurie and the City of San Francisco for the ongoing partnership with Waymo and keeping SF at the forefront of innovation.’ The company now operates in 11 cities and completes more than 500,000 paid rides every week, with an estimated 1,000 robotaxis running in the Bay Area alone.
That scale is precisely what makes the regulatory question pressing. California already operates one of the stricter autonomous vehicle frameworks in the country, requiring companies to clear permit processes run by both the Department of Motor Vehicles and the California Public Utilities Commission (CPUC). Waymo holds three CPUC permit types. Several other operators hold pilot permits, including Nuro, which has secured a CPUC drivered pilot permit for a robotaxi programme being developed with Uber and Lucid. Amazon-owned Zoox and a premium Uber service are among those poised to launch commercial operations in the region.
The Waymo robotaxi regulations Lurie is pushing for would, if adopted, set a precedent that other cities and states could follow. The next major test may come sooner than anyone planned: San Francisco’s events calendar does not get quieter in summer, and the question of whether any fleet of autonomous vehicles can reliably manage a crowd of 100,000 remains, for now, unanswered.
