I have just remembered to add that I have a cousin in her 80's who quit driving cars when her husband got home from Vietnam. She managed to raise 5 kids without driving - can't imagine how because I didn't know her well in those days. A few years ago they moved to a small Texas town, and for some reason they decided that she needed a way to get around when her husband was not well, so they got her a golf cart. I don't know if those are legal on the road everywhere, but it's an interesting choice.
