A few days ago, my brother's truck got hit, and hard, at the back end. A moment sooner, and it would have been a full-on T-bone. The other driver ran a red light. Turned out that driver was an elderly man who was so out of it he didn't even know he'd hit someone...and at 50 MPH, no less! But his wife was with him, and she grabbed the wheel and then turned the ignition off and forced the car over to a moderately safe stop in a shallow ditch.
My brother was not injured, fortunately, and surprisingly, the truck is still drivable, though I rather doubt that the tailgate still opens without the use of explosives.
Truly, there comes a time when a person should not be allowed to drive. It varies from person to person, but I think anyone over 65 should be required to take driving tests every two years, and at 70, make it every year.
But here in FL, the retiree community is huge, and they vote, and they don't want such a sensible idea to become law because it'll inconvenience them and may result in some of them being deprived of their driving privileges. Never mind that only those who are a danger to others by their lack of driving ability are the only ones who actually lose out, the retirees won't even hear of the idea!
Those who need such a program most are those who want it least.
