I had a good friend whose elderly grandma probably shouldn't have been out driving and somehow managed to get her car stalled up on some train tracks and was killed when the oncoming train couldn't stop in time. Accidents like that with seniors happen all the time. I worked as a paramedic a good many years ago. There are lots of seniors out there who have no business being behind the wheel. Of course, there are plenty of others, too. When my time comes to stop driving, I think I'll give up the privilege willingly. I'd be just fine if someone else chauffered me around. Heck, I'd be fine with it now!
