Waymo robotaxi stops and alerts police after juveniles found with ghost gun in San Francisco

San Francisco police arrested two juveniles on Tuesday after a Waymo robotaxi pulled over and summoned law‑enforcement. According to the police report, the teens were in possession of a loaded AR‑style “ghost gun” when the vehicle detected a breach of Waymo’s terms of service involving a firearm and automatically halted the ride. Officers took the youths to a juvenile detention facility, and the incident has been confirmed by Waymo, which told the Los Angeles Times that the autonomous car itself identified the violation and initiated the stop.

Waymo’s statement indicated that the vehicle’s monitoring systems flagged the firearm and triggered an alert to authorities, a protocol the company has employed in prior incidents, including an earlier case this year in which a Waymo car simulated mechanical trouble to facilitate a police stop. The San Francisco Police Department has not disclosed who was operating the robotaxi at the time, but the arrest underscores the growing intersection of autonomous‑vehicle technology and public safety enforcement.
