My tips for winter driving...
STRAP IN! Always wear your seatbelt, remember there are morons abound in the other cars that may hit you.
TAKE YOUR TIME. No need to rush, you won't be going anywhere if you are in a ditch or on your roof.
TIRES! ABS, Traction Control, 4WD, etc. do NOTHING if you can't grip the road. You don't necessarily need dedicated winter tires, but they are better than all seasons. Note: Michelin Latitudes are PATHETIC when it comes to deep snow, you have been warned!
EASY EASY EASY. Easy on the gas, easy on the brakes, easy with the steering wheel. Jerky movements=losing control and/or traction.
Leave 2-3x more distance between you and the car in front of you. If you start to slide, you KNOW you have plenty of time to get back in control...beats a change of underwear and/or body work.
Disable your traction control if you are starting from a dead stop in deep snow.
I have noticed with my Escape that the *** end seems very light and will fishtail extremely easily, watch it going around corners.
These are my 2¢. I lived in Pittsburgh all my life except for 2 college years where I lived near Erie...I know (and love) my snow!
