That takes courage, and I applaud you. I have a similar concern with my father, who is 94, although he has had no accidents. Fortunately he moved recently, and now he rarely drives more than 2 or 3 blocks within his assisted living complex, when he's too tired to walk to dinner. I'm scared to death of even that, but he lives in Florida, where the elderly have free reign. Last year, at the age of 93, he renewed his driver's license for TEN (10) YEARS, solely on the basis of an eye test. That is criminally insane, in my book.
