Like Plato stated, I think it would be much more acceptable to have them use public transportation or being driven around by some other means than causing tragedy. If you look around in your local paper's archives, you'll find countless articles on elderly people just being oblivious to traffic laws and causing an accident resulting in injury/death. If prohibiting people over the age of 75 or whatever from driving unless passing a test saves 8 lives, it's well worth it in my opinion.
