Strange, was chatting with some friends about this only a couple of days ago. Most are cyclists or ex-cyclists. One thing cropped up. The route to drive a four wheel vehicle should be c=via bike - demonstrate you can ride one (!!) and some kind of minr test not for cycling but to qualify for getting a provisional licence. Then small (125) motos, actually pass a proper test, then allowed to start learning to drive cars. The thinking is to get everyone, over time, to realise how surfaces, speed, etc., all affect vehicles of all types. Of course, it will never happen because it's "too expensive" or "not inclusive" e.g give everyone a licence to drive 1500kg of metal about after a simple test. Exceptions for disabled, of course.
It's a nice idea, though....
