Does Dad have to have an accident before someone intervenes and gets him to stop driving?
I understand your frustration, I think figuring out if a parent is legally safe to drive or not is one of the hardest things adult children confront. First, check http://www.caring.com/calculators/state-driving-lawscheck to find out what the vision requirements are -- and if, your father is driving illegally. If he is, having to surrender his license may force him to accept this unwanted change. If he isn't, try to get him evaluated by an occupational therapist (OT) who is a certified driving rehabilitation specialist. The OT could help him maximize driving fitness and safety and plan for his eventual driving retirement. Keep talking about driving safety and fitness. The message will eventually get through and he'll appreciate your love and support even though now it seems fruitless.
