Waymo robotaxis clog San Francisco and one catches fire on a firework on Independence Day

On July 4, 2026, Waymo's robotaxis suffered a large-scale failure in San Francisco: dozens of driverless cars ran out of charge and got stuck in holiday traffic, blocking roads for several hours, and one of them drove over a burning firework and burst into flames.

What happened on Independence Day

On July 4, 2026, during the holiday weekend, dozens of Waymo robotaxis became stuck in traffic jams near the Golden Gate area of San Francisco. Closed streets, holiday celebrations and unusual traffic proved an insurmountable obstacle: the cars got stuck, could not continue and ran out of charge right on the road.

The problem was made worse by the fact that a driverless vehicle with no one aboard cannot deal with the situation on its own: it cannot pull over to the shoulder, call a tow truck or find a charger. As a result, stalled robotaxis became a source of new jams themselves: the cars blocked lanes and waited for evacuation, which was also delayed by holiday traffic. According to The Next Web, the jams caused by drained vehicles lasted several hours.

The fire was a separate incident: one of Waymo's driverless cars drove over a burning firework lying on the roadway and caught fire. It was the most spectacular episode of the weekend: a burning car with no driver became a symbol of the holiday chaos. Details on casualties and the extent of the damage were not reported at the time of publication.

Key facts about the incidents:

• Dozens of robotaxis ran out of charge and stopped in traffic near the Golden Gate area in San Francisco
• Jams caused by the stalled vehicles lasted several hours
• One Waymo driverless car drove over a burning firework and caught fire
• The incidents took place over the holiday weekend of July 4–6, 2026

Why the holiday failure became a reputational crisis

Waymo is a subsidiary of Alphabet (Google's parent company) and effectively the only major operator of commercial robotaxis in the US. After Cruise (a GM division) lost its license in California in 2023 following a series of incidents, Waymo remains the industry's flagship. The service operates in San Francisco, Los Angeles and Phoenix; over several years its vehicles have driven tens of millions of kilometers in autonomous mode.

That is why the July 4 events resonated so strongly. In the words of The Next Web, "Waymo's driverless cars became the top news of the holiday weekend", though not because they worked well. A burning car and hours of traffic jams made of robotaxis are content that spreads instantly online and stays in public memory for a long time.

"Driverless

Waymo cars became the story instead of the technology," writes The Next Web.

The incidents exposed a classic weak spot of autonomous systems: the algorithms are well trained on typical city traffic but fail in abnormal conditions. Holiday chaos, with closed routes, crowds of pedestrians and burning fireworks on the roadway, is exactly the type of scenario for which standard protocols provide no solutions.

For regulators, namely California's CPUC and the federal NHTSA, incidents involving autonomous vehicles inevitably prompt official inquiries. Waymo will have to explain how battery charge was monitored in real time and whether protocols existed for mass battery depletion under peak load.

What this means

The mass failure on Independence Day became both an operational and a reputational problem for Waymo. The company is actively expanding the service's footprint and investing in convincing regulators and the public that its technology is reliable, which is why viral footage of a burning driverless car hits trust disproportionately hard. The next step is a public explanation of what happened and concrete technical measures that can prevent a repeat under similar conditions.
