My 87 year old parents each have their own cars and drive all the time. Neither one of them should be driving. Mom just renewed her Florida divers license— no problem. It’s good for 5 years...
My mom turns 92 this summer. Still drives all over the place. (No - not that “all over the place”!) No more long trips, but she makes it to her doctor’s visist in the snow, lunches, church, concerts, etc.
She will drive the 2 miles from my brother’s house back home at night if she has to. But will usually have one of the other relatives bring her home as she doesn’t like driving at night anymore.
Never had an accident (not even the side of the garage door!), takes some class and test every so often to keep her insurance down too. But she is the exception, and is a very young 92. (She wanted to try to get up on water skis again on her 90th birthday, but we wouldn’t let her!)
