An accident report filed with California's Department of Motor Vehicles says a self-driving car being tested by Google collided with a public bus on Valentine's Day.
The report was written by Google, which has been testing two dozen Lexus SUVs outfitted with sensors and cameras near the tech firm's Silicon Valley headquarters. It was posted Monday on the DMV website.
The car was rolling at 2 mph, the bus at 15 mph.
No one was injured.
Google said its car's safety driver thought the bus would yield. The report does not address fault.
A DMV spokeswoman told The Associated Press the agency hoped to speak with Google Monday about what went wrong. A Google spokesman did not have immediate comment.
