Motorway driving would be super, but you'd be buggered if you live in Scotland/Wales/Devon/Norwich. Thus, it wouldn't really be enforceable unless they made you drive in particular cities (and I suppose you can still drive around without ever needing to use a motorway if you lived in those areas too).
I have to say though, reversing around corners, turning in the road, hill starts and parallel parking are just things that I usually bodge quite well. I am used to doing them and don't need to think about it very much. Emergency stops, however, sneak up on the best of us and therefore these should always be tested in the exam.
What are the views on re-testing drivers? Obviously not to driving test standards (as those are really quite irrelevant once you start on the roads and learn "real" driving skills) but to safe and aware standards? I think a lot of drivers quickly forget how to drive and never evaluate themselves. Driving is seen as too much of a right in my opinion.
