However this is something the AARP crowd will fight to the end over, no matter how many of these incidents occur. Depriving someone of a driver's license is a blow to their independence. My dad lives out in the country for example; I've had to be the chauffeur ever since which he hates. But it's much better than having an accident.
It is a problem with no easy answer. I work with my mother. She has been a good driver all her life and wants to continue. Driving at night is a no-no. We work out her routes to avoid the bad areas. Make three right turns and a left at the light instead of having to make a left across fast moving traffic where there is no light. Shop at Kmart instead of Walmart since the parking lot is so empty!
