The K-rail will work, but one would have to crash like NASCAR racers who lose control on high-bank circuits, by keeping the front wheels turned into the wall.

But to learn that technique would require, possibly, every driver to take some sort of DE course - you won't learn it in regular old high school driver's training - which, as it is, doesn't seem to be offered any more.

Nonetheless, DE courses for new drivers would be a great idea, though no dobut cost prohibitive in many cases.
