My 92 year old dad thinks he can still drive. He recently had an accident (no one was hurt,only property damage). He is stubborn. My 92 year old mother says it is time for him to quit driving. The last time I rode with him (about a month ago) he had good command of the vehicle. He worked hard to get his drivers license renewed last year and passed the written and road test. But things have changed for him physically. I believe he does not want to admit this. The recent accident should be his wakeup call. It is for the family.
