No, he should keep driving until he kills someone you love. After all, he's only 85.
I know a lady who is now wasting away in a nursing home. However, she also was 85 and still driving at the time she told me she stopped at a light and could not remember where she was. After a bit the person behind her beeped his horn to get her to move. She started driving slowly and then suddenly knew where she was and drove slowly home. It's wonderful to want to be older and independent, but common sense must prevail and perhaps 85 years old and common sense don't mix.

There you are I knew you'd show up. Guess a mistake is as good as a death warrant with you. I've made the same mistake as Mr. Glenn once upon a time, you gonna take my license too?
