On December 27, a Waymo robotaxi collided with a Serve Robotics delivery robot in West Hollywood, raising concerns about the safety of autonomous vehicles. A video circulating online captured the incident, where the delivery robot appeared to violate a red light before being struck. Waymo's spokesperson clarified that their system identified the robot as an inanimate object, applying brakes before the contact occurred at 4 mph. Neither vehicle was damaged, and the collision has prompted discussions about liability in future incidents. Serve confirmed this was their first collision with a robotaxi and that the delivery robot was under remote supervision.
