This reminds me of a Planet Money episode (a great podcast). http://www.npr.org/sections/money/2015/07/29/427467598/episo... . In it, they talk about people not wanting to ride elevators not controlled by a human operator, and how companies got people to ride them. In the same way as elevators, people will eventually adapt to self driving cars even if the industry needs something like a manual mode for emergencies or a big red button.
