My mother is deceased and my father is in a VET's hospital but my father-in-law is a menace. Of course you cannot tell him that his driving ability is deteriorating. We were at least able to keep him from making long trips. He used to drive to Florida but now he will fly.

I noticed that he is not driving as much.

I think it is very hard on the family member who is trying to take away the license of a parent. My husband and sister-in-law do not want to admit that it's a problem.

And unless the DMV revokes his license, he will just go down there and get another if his is taken away. We even tried taking the car keys but he just calls a locksmith. His problem is intermitting.
