People set a model from Google sister company Waymo on fire on the street. The Waymo robotaxi was stranded on a street blocked by a crowd during Chinese New Year celebrations in Chinatown on Saturday evening.

San Francisco became a unique testing ground for self-driving taxis last year. Waymo and General Motors subsidiary Cruise received permission from a California regulator this summer to offer their driverless transportation services throughout the city. Critics and authorities complain, among other things, that the vehicles often block traffic.
