I agree that for the vast majority of folks self-driving cars are not needed.
However, the baby boomers are gonna keep getting older and we are eventually going to be menaces on the road.
At some point it will be safer to have a self-driving car than a ninety five year old geezer at the while.
Interestingly, I think ride-sharing services like Uber and Lyft have diminished the appeal of self-driving cars for the elderly. I work with one client that is developing a phone-based interface for Uber and Lyft -- so they can be used by elderly people who have no idea what a smartphone app is.
That 95yo geezer shouldn’t be at the wheel:
