The government and any parts therein cannot fix people's moral or lack of moral choices and they shouldn't.  If individuals are doing stupid dangerous activities with driver less cars no amount of government regulation will fix stupid.  Besides the government always waits too long to get anything done in a timely matter and costs triple or more then proposed budget plans!.

Look at Amttrak do you want that for autonomous vehicles?  At least you can choose not to ride Amtrak!
