I couldn't agree more, old people are some of the most dangerous car drivers and here in the UK get the most offences for driving under influence of medication/drugs. I think that after a certain age you should be retested to check driving ability and how safely it is done, if you can't see that well or don't drive fast enough (like the idiot old people going on motorways and not driving fast enough, police bollock them thankfully) no liscence for you!  I did want to report my grandad to the DVLA but my mother said she would disown me if I did, my grandad could hardly work the pedals from his severe arthritis and he drove at stupidly low speeds, the only reason I didn't do it secretly was that he stopped driving as much and even when he did he only went to a shop a mile or so away, if he was still fully driving I would have. I love and miss my grandad but he was dangerous to others on the road, that takes precedence over family loyalty, family loyalty would mean nothing in a court if he had killed someone.
