It's wrong to criticise without knowing the full facts, but there again this is VD so doesn't count!
My father in law is 82 years old, took his advanced driving test at 77 and still involved with the IAM weekly meeting etc.
Unless you knew him you would not know he was 82.
OK so 93 is a ripe old age, but we do not know the person involved has his full faculties or was half dead.
Even so, it shouldn't be about age, more to do with ability to drive, thats the thing that should be verified at any age and not just over 70's.
