how should you stop if you go into a skid? Instinct tells me to slam my foot on the brake but someone once told me that this won't help.
Find a nice quite back road (a disused ind estate / shut down chav estate etc) where the gritter wagon has been told not to go because of the salt draught.
Drive at a slow speed and slam the brakes on. Steer in the direction that you want to go. See what happens! You won't get hurt if your slow enough, then build up.
Eventually, what was really scary becomes really exciting...!
