Self-driving cars might be the future, but not everyone is a fan. Some people are apprehensive about their safety. Others, like some of the FindLaw staff, are annoyed at them being too safe (is it really necessary to stop and wait behind every USPS truck delivering mail?!).
But one thing most of us probably didn’t anticipate from the admittedly cute little white sedans? Vigilante justice. Last week in the Bay Area, that’s sort of what went down: Waymo effectively delivered what it thought were two juvenile delinquents to the police. FindLaw breaks it down.
Waymo’s Got Eyes Everywhere
Waymo robotaxis are still a novelty in most of the country, so it’s worth laying some groundwork before diving into the San Mateo story.
Waymo is Alphabet’s autonomous vehicle subsidiary — the company behind those white, sensor‑crowned vehicles you may have seen gliding through parts of San Francisco and Phoenix without anyone behind the wheel. They operate as robotaxis: you summon one through an app, it pulls up, the doors unlock, and you ride to your destination while the car’s automated “driver” handles the road.
For many riders, the experience feels like a slightly futuristic version of calling an Uber, just minus the human in the front seat. In some cities, like Atlanta and Austin, Uber and Waymo literally work together: you can get a Waymo robotaxi through the Uber app instead of using Waymo’s own app.
Waymo equips its vehicles with a dense array of sensors designed to give the car a 360‑degree, high‑resolution view of the world around it. That includes lidar, radar, and, crucially, up to 29 cameras positioned around the vehicle. These cameras capture detailed video in a variety of lighting conditions and angles, so the system can see lane markings, pedestrians, cyclists, and other cars. Importantly for this story, it can also tell what’s happening inside and right around the cabin.
Those interior and exterior cameras aren’t just there for the algorithms. The footage they collect can be viewed later by human employees, and sometimes in real time by remote operators overseeing rides. In practice, that means every trip can generate a visual record of the passenger’s behavior, their companions, and any activity near the vehicle. This is certainly useful for diagnosing problems or protecting the car from damage, but it’s also potentially valuable as evidence in disputes or criminal investigations.
And that’s exactly what happened last week in San Mateo.
The San Mateo Incident
On Monday evening July 6, two 15-year-olds were riding in a Waymo robotaxi and allegedly drinking alcohol. But that’s not all: according to police, they were also firing beads from a toy gun (reportedly an Orbeez‑style gel blaster) out of the car’s window. Waymo’s system flagged the behavior as dangerous and triggered what the company calls a “safety response.”
A remote Waymo employee monitoring the live camera feeds then contacted San Mateo police to report what looked like a firearm being fired from a moving vehicle with possibly intoxicated occupants. A spokesperson for the San Mateo Police Department said they received a report that a “firearm” was being shot from a moving vehicle and that the occupants might be intoxicated, which led them to treat the stop as a high‑risk scenario.
After that call, Waymo’s remote operators used their controls to disable the robotaxi and route it to a nearby parking lot, where they had it stop and wait. Once the car was stationary, officers arrived on scene and carried out what they described as a high-risk traffic stop — guns drawn, commands shouted, and the teens detained until the situation was under control.
Later, the police department posted about the incident on Facebook with the line, “Parents, do you know where your teens are? @Waymo does!” The teens were ultimately released to their parents, and potential charges such as underage drinking are still pending as police review video from inside the car.
A Dashcam Detective?
The same cameras that let Waymo “see” what was happening inside the car are now central to what happens next in the San Mateo case. Police have said they’re waiting on video from Waymo before deciding whether to charge the teens. The entire incident may well be replayed and scrutinized frame by frame.
This isn’t the first time Waymo footage has played a starring role in law enforcement. In prior cases, police have obtained video from nearby Waymo vehicles to help investigate hit‑and‑runs and other crimes, effectively turning the driverless vehicles into mobile crime‑scene cameras.
The obvious takeaway is that the same cameras Waymo uses to keep its cars safe also create video that police can request and use as evidence when investigating a crash or crime. But the even bigger deal is that instead of pulling footage after the fact, Waymo’s cameras helped trigger the police response in the moment.
All of this raises an uncomfortable question: how private does a self-driving Waymo ride feel compared to how private it actually is? For many people, being in a car (especially one without a driver) feels like a semi‑private bubble. Legally, riders may have technically consented to being surveilled recorded by clicking through terms of service or privacy notices in the app. But most people don’t read those documents closely, and even fewer internalize the idea that their ride could be stopped, reported, and their behavior later reviewed by police.
As self‑driving cars roll further into everyday life, the real question isn’t just whether we trust them to drive; it’s whether we’re ready for them to decide when our “private” rides become police business.
