I hate the W-cars in the snow. Well more specifically the Luminas and 00-05 Impalas. Feels like the back end of them is just to light. Also, being from Pgh and dealing with winter driving regularly, I would say that the hardest part is not 6 or 12 inches of snow, but unsalted or poorly plowed roads and ice with 2 or 3 inches on them. I agree that tires have a lot to do with it, but also the style and ability of driver is a big part too. A driver has to handle the abilities of a rwd car differently then they would a fwd car. Look how many morons roll suv's every year.
