There's a lot to be said for keeping a good distance between you and the person in front of you, so you don't have to hit the brakes every time the idiot in front of you barely touches the brake petal...the way I slow down on snow/ice is I run with the OD off shift into 2nd and 1st if necessary, with the breaks thrown in for good measure. So I don't break my shit.

Edited to fix the spelling of brakes for Kaiser spelling nazi
