Reminds me of the one about the bloke who says he wants to die peacefully in his sleep like his father did, rather than die screaming and yelling like all the passengers on his bus!
To my mind there is a narrow path that lies between "ageism" and Political Correctness. It is wrong to discriminate against able people on account of their age, but it is equally wrong to be blinkered to the fact that people do age and their faculties and capabilites reduce.
Perhaps one of the biggest problems is that ageing happens at a hugely different rate in different people. As a few on the forum may be aware I had the very great honour of navigating in Cooperman's rally car the other week, and can quite honestly state that his skill level and awareness are substantially better than vast majority of drivers 40 years younger! By his results he remains in the top 5% of competitors
of any age. Yet others seem to be well on the way to senility by the age of 50.
My preferred solution would be that every driver is required to take some form of re-test every 3-5 years, but that the content and duration of the test would be varied according to their age and experience. That way we deal with each case as an individual, which to my mind treads precisely along the narrow path I mentioned above.
And so as not to be discriminatory this scheme should be state funded as a safety service to all road users; partially out of the massive tax take from motorists, and partly out of the massive saving to the NHS that a decent educational road safety scheme would surely yield.
