The key, I think, to driving on snow is to be smooth. No sudden turns, no sudden braking, no sudden acceleration -- all these are recipes for loss of control. Naturally, one has to drive a bit slower, because faster speeds increase the probability that you will need to make a sudden maneuver. That doesn't mean you have to drive slowly; just be cautious, give other cars a wide berth, and try to maintain a constant speed that is safe for the conditions.
Driving in this weather makes me nervous. One, I know that the percentage of idiotic driving behavior increases sharply. Two, I drive a pickup truck. There seems to be a misconception that trucks handle well in this sort of weather. There couldn't be more fetid bullshit out there! Pick-up trucks have no weight in the back ... unless you've piled sandbags or other very heavy items onto the truck bed. Therefore, they are more prone to spinning out. To compound things, my truck is rear-wheel drive. That means that if I don't get a good grip on the road with my rear tires (for example, on ice or snow, especially going uphill), my rear will drive right by my front, spinning out, rather than push the front. I can drive slightly aggressively in good driving conditions because I am intimately aware of how my truck will respond. However, bad weather takes all that out of the equation, as the truck's response on a slippery surface can be so unpredictable.
<sigh> I can't wait for this snow to end!
