This situation is not any different from a ticket issued by a speed camera. Since the camera can’t tell who is driving, the fine is issued to the owner of the vehicle (determined by the license plate). The owner is legally responsible for the fine. The only difference between a speed camera ticket and a ticket given by an officer in person is that the speed camera does not result in penalties for driving infraction (eg points on a license or license suspension) only fines. A ticket to a driverless taxi should work the same way; the citation goes to the owner of the vehicle.
