There’s more to it, elderly who can’t drive wind up stranded & isolated which is a problem in itself. If we look the other way when they slowly become unfit to drive, we aren’t forced to solve those other problems.
Yeah, this is a good point. There are a lot of lonely and sad old people out there, many of them living in increasingly hoarder-y situations as they age and lose executive function. We go on some pretty sad medical calls/welfare checks. Check in on your old relatives.
