first of the ebrake manuver does work, BUT before you try it in real driveing conditions practice in a parking lot.
The statement is true practice makes perfece, you'll never be 100% perfect winter driver(to many variable to put in) but you can come close. So go to that parking lot and practice skid controll.
SNOW TIRES, tall and skinny.
start in the highest gear possible, your not at the races to see how can get to speed first, This allows the most out of the traction you do have.
Speaking of traction never think you have over 50% traction in winter, because you don't.
get a winter servival kit. and if you do get stuck don't leave the heat on. Turn off and on the car to heat your self up. KNOW WERE YOUR TOW CLAPS ARE AT, or get a T-hook, This will save a lot of pain(long story, I was young in a ditch, log chain came loose tore a hole in the tranny.)
basically drive like the grandma in your naborhood, always slow, and precashus.
