[Margaret Pilkington]

I think it is too easy to fall into the trap of a knee jerk reaction like this, and generalise about the fitness for particular activities in the elderly.
Some people are a hazard at 20 because they haven't enough experience of life, and will take unacceptable risks.......I wonder if you would be suggesting this action if the driver had been a boy/girl racer....I think perhaps not.
A lot of elderly people will recognise their own failings and drive according to these weaknesses........I know a man who was 92 and still drove regularly, and safely.....his wife had Alzheimers disease and if he had not had his vehicle to get her to places then he would have been seriously inconvenienced......this man died recently and was driving fairly regularly up to the time he died.

Each case should be judged on its merits.
