When my grandfather was in his early 80s, he was driving back from his regular morning swim at a friend’s pool at 630am when the police pulled him over. They said that he had been driving erratically and they had been trying to get his attention with their sirens for a few blocks. The police took him home in the back of the police car and that was the end of his driving career. Looking back at the situation, I think the whole family was aware of the incremental degradation of his faculties over the previous few years, and perhaps there should have been an earlier intervention. It was lucky, under the circumstances, that no one was hurt by his poor driving skills in his last few years behind the wheel.
