What is the fastest way to make a 90 degree turn on a slippery road?

physics/skid.s

For higher speeds (measured at a small distance from the point of initiation
of a sharp turn) the fastest way round is to "outside loop" - that is, steer
away from the curve, and do a skidding 270.

This technique is taught in advanced driving schools.
