Googling for this, apparently Tesla do try to recognize police gestures, and are getting better at it.

I wonder who gets the ticket when a driverless car does break the law and get stopped by police? If it's a Taxi service (maybe without a passenger in the car) then maybe it'd the service, but that's a bit different than issuing a traffic ticket to a driver (where there's points as well as a fine).

What if it's a privately owner car - would the ticket go to the car owner, or to the company that built the car ?!
