The California Highway Patrol tweeted a photo of a man found in his Tesla stalled on the Bay Bridge.
Officers say he failed a sobriety test but told them it didn't matter because his car was on auto-pilot.
The CHP says even on auto-pilot, the Tesla requires some kind of response from a human being at certain intervals.
If that doesn't happen, the car slowly comes to a stop and that's apparently what happened.
