Waymo robotaxis face fireworks and gridlock on July 4 in SF

A viral video appears to show a Waymo robotaxi driving through an exploding firework in a San Francisco intersection on July 4, 2026, while separate incidents left another unoccupied Waymo on fire and many vehicles caught in holiday traffic delays. No injuries were reported, but the footage is fueling fresh scrutiny of how autonomous fleets perform during major city events.

Key Takeaways

• KRON4 published viewer video of a Waymo driving through an exploding firework as a passenger filmed from inside the car.
• CBS News reported that Waymo is evaluating multiple July 4 incidents, including one unoccupied vehicle that caught fire after driving over a small firework.
• NBC Bay Area said that fire happened near the 1200 block of Connecticut Street; Waymo coordinated with the San Francisco Fire Department to remove the damaged car.
• A separate rider video shared with CBS showed a Waymo driving over an illegal firework without damage; the company said it reached out to check on the passenger.
• Holiday congestion also disrupted Waymo operations, and Mayor Daniel Lurie's office acknowledged delays for crowds of more than 100,000 people.

What did the KRON4 video show?

According to KRON4, a video sent to the station seems to show a Waymo car driving through an exploding firework on Saturday evening. The clip captures a passenger inside the autonomous vehicle filming out the window.

In the footage, a person on the sidewalk appears to light a firework in an intersection. As the device begins to explode, the Waymo continues forward through the burst. The station's report frames the moment alongside broader July 4 disruptions involving the company's vehicles.

For readers tracking autonomous mobility as a business story, the clip highlights operational risk during unpredictable street conditions. Major holidays combine crowds, illegal pyrotechnics, and sudden road hazards that human drivers often avoid by instinct.

How many Waymo fireworks incidents happened on July 4?

CBS News reported that Waymo is evaluating a couple of incidents on the Fourth of July in San Francisco in which its autonomous vehicles drove over fireworks. One involved an unoccupied vehicle that drove over a small firework in the street and caught fire.

In a separate case, a video on social media from a Waymo rider showed another vehicle driving over what the company called an illegal firework in the street. Waymo told CBS that no injuries were reported in that incident and that the vehicle was not damaged.

The company added that it reached out to the rider to check in on them. That distinction matters: one car was empty and burned, while the other carried a passenger through an active detonation yet reportedly emerged unscathed.

Where did the Waymo vehicle catch fire?

NBC Bay Area reported that an unoccupied Waymo autonomous vehicle caught fire Saturday evening after driving over a small firework in a San Francisco roadway. The incident occurred near the 1200 block of Connecticut Street.

No one was inside the self-driving car at the time, and no injuries were reported. Waymo told the station it coordinated with the San Francisco Fire Department and local authorities to safely remove the damaged vehicle from the scene.

CBS News similarly reported that the fire department and local authorities helped put the fire out and remove the vehicle from the road after it drove over a small firework in the street.

Why did Waymo vehicles contribute to July 4 delays?

Beyond the fireworks videos, CBS News noted that some Waymos had their operations disrupted on July Fourth due to traffic. A Waymo spokesperson said its roadside assistance team cleared vehicles from affected areas.

San Francisco Mayor Daniel Lurie's office issued a statement about Saturday night traffic, saying safety was the top priority. The mayor's office said that with more than 100,000 people in the area, some residents experienced delays getting home.

Lurie's office added that the city will have conversations with public and private partners to ensure the experience is smoother next time. For anyone following robotaxi reliability during peak demand, holiday gridlock is a recurring stress test.

What is Waymo saying about the incidents?

Waymo told CBS that it is evaluating and learning from events like this. The company said it remains committed to keeping riders safe and earning the trust of the public.

That trust question sits at the center of the autonomous-vehicle business narrative. Viral holiday footage travels fast and can shape public perception overnight, even when companies report no injuries.

Readers who follow Wealth Hacks & Passive Income coverage know that headline risk is not the same as balance-sheet risk. Still, repeated edge-case videos can influence regulation, insurance costs, and the pace of deployment.

Should Waymo observers read too much into one holiday weekend?

A single July 4 weekend does not settle the debate over driverless cars in dense urban cores. The sources agree on the core facts: fireworks contact, one fire, one undamaged rider trip, no reported injuries, and significant traffic friction.

What the weekend does provide is a real-world checklist. Can empty vehicles avoid stray hazards? How quickly can roadside teams recover stalled cars when a city hosts six-figure crowds? Do passengers feel safe when algorithms choose forward motion over hesitation?

Waymo's own statement to CBS points toward review rather than dismissal. Until the company publishes more detail, observers are left with video evidence and official acknowledgments that the fleet did not glide through Independence Day untouched.

What happens next?

Waymo said it coordinated with first responders on the Connecticut Street fire and contacted the rider from the second fireworks video. The company told CBS it is evaluating the incidents and learning from them.

Mayor Lurie's office signaled upcoming talks with partners about smoother large-event operations. KRON4's viewer video will likely keep circulating as a shorthand for how robotaxis behave when celebrations spill into traffic lanes.

For now, the story is defined by what cameras captured and what the company confirmed: a Waymo drove through an exploding firework on video, another burned after rolling over a small device, and holiday congestion added delays on top of the sparks.
