My dad is 93 and can no longer drive independently. He lives in a semi-rural area that is not well served by traditional taxi companies, and so he is severely limited in terms of getting around.<p>I think there may be some opportunity to serve elderly people like him, but the fact is, there is a wide range of technical ability among the elderly. Even in his 70s and 80s, my dad could barely handle the complexity of a flip phone.<p>And while there are other elderly people who are more tech-savvy, I think the big shift is going to occur when self-driving cars become available. That's going to open up a lot of mobility for people who can't drive because of age, disability, etc.
