A man who was found passed out behind the wheel of his Tesla on the Bay Bridge in San Francisco on Friday was arrested on suspicion of drunken driving, officials said.

The man told officers his Tesla had been set on autopilot, the California Highway Patrol said in a tweet.

Authorities determined his blood-alcohol concentration was more than two times the legal limit, according to CHP. He was subsequently taken into custody.

The Tesla was towed, officials said.

“No it didn’t drive itself to the tow yard,” the CHP joked on Twitter.
