The coefficient of
static friction for rubber on ice is approximately 0.25. The coefficient of
kinetic friction for rubber on ice is approximately 0.15. The key to accelerating/decelerating/cornering is to control the wheels so that you don't enter the kinetic phase and suffer this 60% loss of friction.
(For comparison, the coefficient of kinetic friction for rubber on wet asphalt is 0.25. The coefficient of static friction for rubber on dry asphalt (which is what we'd all prefer) is around 1.)
