The technical term for this phenomena is called "Wheeeeeeeeeeeeeee!"

A good rant on the physics of "go" verses the physics of "stop"

If anything, 4 wheel drive merely allows you to get yourself into more dangerous situations. We saw a Porsche 911 fishtailing all over the road. He was aware of his limitations in the snow and was going 30 mph. His torquey, rear wheel drive system had little in the way of traction in the snow -- and he knew it. He crept along in the right lane and still ran into some trouble. (On the other hand, I drove our rear wheel drive SLK home from White Plains Christmas Day 2002 in 6 inches of snow -- it took 3 and half hours versus the usual 60 minutes. I had no problem, but that's mostly because I am not an idiot.)

Now back to our 70 mph snow fools: In the event of loss of traction -- not too hard to imagine in 4 inches of snow -- you are merely a two ton hunk of steel sliding across a frictionless surface until you either regain directional control or run into some mass which stops you. Your Anti-Lock Brake System (ABS) is useless when your tires cannot make contact with the pavement. Modulating brake lock up when snowplaning on a 2 inch cushion of white stuff does you no good whatsoever. The technical term for this phenomena is called "Wheeeeeeeeeeeeeee!"
