Passing the driving test ensures you have a basic level of control and awareness, but it doesn't train you in good judgement - that comes with experience (and a lot of that comes from bad judgement). I once did an Advanced Driving course: although I didn't take the actual test, I like to think that my driving did improve - on a good day at least - and I would recommend it to anyone. In fact, as I have said elsewhere, it ought to be obligatory for all drivers after a few years' experience.

How though to enforce such a thing? Require non-advanced drivers to display P plates? Limit the power and weight of the vehicles they can drive? Maybe the insurance companies can help here. The other problem is of course international driving - I can see the Swiss and Germans taking to such a scheme, but the French? Not to mention the Italians!
