It would probably be more efficient, if there was that much concern over learning in all conditions, to set up regional 'learning centers' with skid pans, sprinklers etc. and mandate that you have to have at least 2 hours (as a random figure) of your lesson time at one of these, learning the more specialist/uncontrollable elements.

There are plenty of skid pans about and courses are available as part of advanced driving instruction.
Then again, some people are incapable of controlling their own bodies at times so not sure how well it would go for them learning to control a car sliding in the wet
