I can conclude based on using FSD every single day. I've hit issues just like this, as well as police directing. And it's completely fine.
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 ?!
