Waymo Robotaxis Stalled During Fourth of July Gridlock in San Francisco
7/6/2026, 8:50:47 AM
Incident Overview
On the night of July 4, 2026, after the Golden Gate Bridge fireworks, severe traffic congestion and unplanned road closures in northern San Francisco immobilized a number of Waymo robotaxis. Several vehicles ran out of charge while idling, were towed, and one unit drove over an illegal firework, igniting a brief blaze. No passengers or bystanders were injured, but the fleet’s operations were halted for hours.
Background & Context
Waymo’s fleet has previously been vulnerable to citywide disruptions; a December 2025 power outage that disabled traffic signals left hundreds of its vehicles stranded at intersections, prompting a temporary service pause. The July incident tested the same resilience under mass-event conditions.
Key Figures & Groups
Key participants include Waymo (operating 577 robotaxis and ~500 000 weekly rides), spokesperson Chris Bonelli, San Francisco Mayor Daniel Lurie, his press secretary Charles Lutvak, and local emergency services.
Data Snapshot
Reports vary, citing “dozens” to “at least a dozen” Waymo cars stuck. Battery depletion forced several to be loaded onto flatbed trucks. Firefighters logged over 500 calls, including four fireworks-related wildfires and two non-Waymo injuries. More than 100 000 people attended the fireworks.
Official Statements & Responses
Waymo said the gridlock and road closures caused “major traffic disruptions, a high volume of travelers, and unplanned road closures,” and that its roadside-assistance team worked with authorities to clear the vehicles while evaluating ways to strengthen resilience. Mayor Lurie’s office stressed public safety, acknowledged commuter delays, and pledged discussions with public-private partners to improve future events.
Criticism & Opposition
Riders voiced safety concerns. Rose Peterson said the vehicle’s reaction to fireworks “needs to be more sensitive to anything that can come into the path of the road.” Dave Guingona reported passengers yelling at driverless cars, and Captain Jonathan Baxter warned the incident could have had a far worse outcome.
Conflicting Reports & Gaps
Sources differ on the exact count of affected Waymo cars—some cite “dozens,” others “at least a dozen.” Reports also conflict on fire damage; one account says a vehicle caught fire, another describes it as unscathed.
