My mom is turning 80 this year and I was just having this same conversation *sigh*. I certainly want her, and others to be safe, but it's sad to see the driving go.

I personally have had some medical recovery things where I could not drive by doc's orders. Omg, it was awful! That loss of independence is depressing.

But, cars can become two ton killing machines when they go bad. Glad your dad has the sense to know to withdraw. My mom does as well. Just dirves the minimum (not at night, no free ways, etc.). But, my FIL on the other hand does not. It scares me.
