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 sounds good—I do think that self-driving vehicle technology will gradually improve—and for those of us who live out in the sticks that is what we really want.
There are going to be more and more industries catering to the old timers—demography is destiny.
