It's wrong that to drive all you have to do is pass a test and then you can do what you like for decades and unless you fuck up repeatedly or spectacularly enough to lose your licence, no-one can stop you. If you passed your test 20/30/40+ years ago, cars and road conditions have changed so much. It's not an ageist thing either - some experienced drivers will be perfectly competent and better than younger or inexperienced drivers.
All other kinds of machinery operation (fork lift trucks etc, require regular refresher training). Why not car driving?
I think there should be a refresher session and eyesight test every 10 years, where you either pass to continue, require some minimal extra tutition to carry on if you are slightly bad, or if you are so terrible/dangerous, lose your licence until you can pass a full test again.
Yes, we would need more resources, but the cost would be covered by the fees. Even if it was £250 every 10 years, that's less than 50 pence a week, so trivial for anyone running a car.
The cost would be tiny compared with all the other costs of running a car and insurance costs would probably reduce if there were fewer accidents. Deaths and serious injuries would also reduce hopfully.
I'm old enough to have a licence that includes fairly large vehicles and/or trailers, but I would never drive anything bigger than a medium sized van, because I know I cannot do it safely. We have a caravan and I would never be able to manouvere it safely.
My DM has a driving licence but hasn't driven for years and has probably forgotten how to do so. But there is nothing to stop her buying a car and causing all sorts of mayhem in it.
