Options are a lot more limited for folks who can’t drive. My mom is in her 80’s still living independently in a rural setting, but we all know — herself included — that she’s approaching the point when she shouldn’t be driving. Where she lives there are no other means of transportation that are realistic for someone her age.
That means moving somewhere that has public transportation. It doesn’t have to be a major city, but it will have a higher population density than where she is now.
Independence for elderly rural folks is one benefit I see to self-driving vehicles. Having one as a driverless taxi in a small town could help a lot of folks stay in their homes longer.
