If a driverless car was in a similar price band to a normal car I would buy one (assuming safe ofcourse).
I once figured out that a self-driving feature would be worth about $5k/year for me.
If you are the parent of young children, how much is it worth? A car that can take the 4th graders to baseball practice while you work on your second grade girl's homework with her? Pretty valuable. How about a car that can pick up your 12 year old and her friends and take them to Lisa's house for a pool party? Sure, version one won't be allowed on the road without a licensed driver - but what about version 4.0?
And if that's not your cup of tea, what about your 16 year old kid? How much would it be worth to have them being driven by Robo-Morgan Freeman instead of their 16 year old friend who decided to try shotgunning beer for the first time?
Or what about the grandfather who shouldn't be driving any more? We had to go to the state to get my grandfather's license pulled as he progressed into his 80's because he was a menace and a danger to everyone on the road. We paid a cousin to be his driver so he could have some mobility, but he absolutely hated being dependent on someone else and he hated us for taking his autonomy. Self-driving cars take that entire problem off the table.
Yeah, people will definitely buy these things.
