My Mum was a perfectly good driver, but at the age of 74 decided that it was time she stopped driving. I really admired her for making this decision. It did help though that she would have had to face driving on the opposite side of the road to the one she was used to. She had previously lived in Germany. Makes me wonder though -just how will I get on without a car when I reach the age where I feel it is time to give up driving? My car is a major part of my independence! A very frightening thought!!! As for retaking the test at a certain age? - I think it is a good idea, but ,perhaps should be free and include a hearing, reaction and eyesight test.
