I remember a snowstorm in Detroit a few years ago. The scene would have been tragic, but thankfully no one was hurt, so it was somewhat funny. The reporter was standing with a highway overpass in the background. Along comes a little midsize sedan, slowly making its way down the highway. No problem. And another. Then comes an SUV at breakneck speed, spinning out, and rolling down the embankment. Driver gets out unharmed(thanks to the 4 feet of snow). Another small car - no problem. Wait, here comes another large SUV rolling down the embankment. And another. And another.
By the end of the newscasts, there were a dozen or so SUVs that had rolled down the embankment, yet not a single car.
SUVs WILL get you through the snow. They will NOT allow you to go any faster than in a comparable vehicle. You still need just as far to brake (or even more than a standard car), and your turning ability is generally worse than a car.
