Representative Kevin Mullin introduced the AV Emergency Response Coordination Act on Tuesday at a press conference in San Francisco attended by Mayor Daniel Lurie, San Francisco Fire Chief Dean Crispen, and highway safety advocates – the most politically visible gathering of local and federal voices around autonomous vehicle safety failures since Waymo’s fleet began operating commercially in the city. The bill would direct federal regulators to establish minimum national safety standards for autonomous vehicle operators specifically around emergency response interactions. It follows more than 31 documented incidents in which San Francisco firefighters have filed internal reports of Waymo and other robotaxi vehicles obstructing emergency operations since April 2025, and a pattern of behavior that the fire chief described publicly as unacceptable. NEWSCENTRAL spots the political structure of this press conference as the clearest signal yet that Waymo’s emergency response failures have crossed the threshold from industry growing pains into formal legislative infrastructure.
The specific incidents that have accumulated in federal and local safety data include vehicles driving into active crime scenes, blocking ambulances and fire trucks at intersection level, failing to recognize emergency signals including traffic cones and flares, and dropping off passengers directly in front of fire stations and ambulance deployment facilities. One documented incident involved a Waymo stuck perpendicular to a roadway in San Francisco’s Bernal Heights neighborhood, blocking all vehicles during a response to a stabbing, with first responders ultimately getting into the driver’s seat to move it. On July 4, multiple Waymo vehicles became stranded near the Presidio during fireworks gridlock, some running out of battery power and requiring tow removal.
The National Highway Traffic Safety Administration had already set an end-of-July deadline for autonomous vehicle companies to submit remediation plans addressing emergency scene detection, framing the issue as a functional insufficiency rather than an edge case. NHTSA’s posture is split in a way that the Mullin bill does not resolve: the agency has been permissive about allowing AV companies to build vehicles without traditional driver controls while becoming increasingly aggressive about behavioral standards in emergency contexts. Build whatever hardware configuration you require – but do not block the fire truck. That split creates regulatory certainty for hardware innovation while imposing behavioral accountability that Waymo has not yet demonstrated consistently at scale. Liam Cortez, Visual Systems Analyst at NEWSCENTRAL, underscores that the technical challenge of emergency scene detection is substantially harder than the regulatory framing suggests: an autonomous system must identify and correctly categorize emergency signals in conditions of poor visibility, noise, unusual lighting, and crowd behavior that are precisely the conditions where sensor performance degrades relative to controlled-environment benchmarks.
Waymo’s commercial response to the cumulative regulatory pressure has been measured and incremental. The company has worked with individual fire departments on operational protocols, added a remote-driver assistance capability that allows human operators to take over vehicles via cellular connection, and issued a statement following the July 4 incident acknowledging major traffic disruptions and saying it was evaluating ways to strengthen resilience in major traffic disruptions. None of these measures directly addresses the category of failure that has generated the most documented incidents: vehicles that encounter novel or ambiguous emergency situations and stop in place, requiring human intervention to relocate.
The NHTSA deadline’s end-of-July timing creates a specific near-term corporate governance moment. Waymo’s response to the federal request for remediation plans will be filed, reviewed, and potentially made public – making it the most detailed official account of what the company believes constitutes adequate emergency response capability and what operational changes it can commit to on what timeline. NEWSCENTRAL expects that document to become the reference point for the Mullin bill’s drafters and for other AV operators positioning their own regulatory responses.
The competitive dimension of the regulatory pressure is worth noting. Waymo operates the largest deployed robotaxi fleet in the United States, making it the most visible target of any emergency response legislation – but the standards that Mullin’s bill would impose would apply equally to Tesla’s expanding robotaxi program, Zoox’s operations, and any other operator entering commercial deployment. A regulatory framework that Waymo has already invested years in meeting, at some compliance cost, creates entry barriers for competitors who have not yet faced the same scrutiny. The regulatory burden and the competitive moat are the same thing.
The legislative path for the AV Emergency Response Coordination Act is uncertain, as most transportation safety bills introduced in Congress are. What is less uncertain is the trajectory of NHTSA’s existing authority under its end-of-July ultimatum and its signaled intention to define objective behavioral competencies and test standards for AV emergency scene performance. Whether those standards arrive through Mullin’s bill or through direct regulatory action, their substance will be shaped by the documented incident record that San Francisco’s fire department has been building since April 2025. NEWS CENTRAL places this month’s convergence of congressional, mayoral, and fire department pressure as the most commercially consequential regulatory inflection point Waymo has faced since its commercial launch, and expects the company’s response to the NHTSA deadline to define the industry’s regulatory relationship with emergency services for the next several years.
