Young kids struggle to get driving tests as it is. My grandson was lucky in that he was in a situation where has was able to put his name down for cancellations so I don’t see how they’d be able to start testing over 70’s too. I’ve never liked driving on motorways and our family life evolved in that my husband did holiday driving and long distance stuff and I did shopping, children’s taxi service ( not just my kids but, as a night owl I was always picking the village kids up after parties and concerts etc). My partner, who, as a rep has driven all over the country’ says he feels perfectly safe with me driving ( unlike with his uber confident ex wife who drove very very fast). I’m very old school, try to be courteous to other drivers, give way to people, watch out for kids and dogs and cats. And yet I feel I’m being pressurised into not driving ( something that would cause major problems, not just with my life but with my families, too. No more child minding or dog sitting). We adapt our lives as we get older in many ways. Just avoiding driving at night or on motorways shouldn’t mean that we can’t drive to the shops or the park. Our eyesight and reaction times can’t possibly be as good as when we were young. But that is counter balanced by our experience. I do think that we should have official medical and eye tests, though. I have to wear distance glasses for driving even though I don’t see any difference in my distance vision until I put the glasses on. I even need my car to go to the post office now that so many rural ones have been closed down.
