I will preach 4 wheel drives as the day is long, but in the hands of the inexperienced, it could be deadly. Yes it is true you can go faster in the snow and hold corners and generally get more traction, .but your vehicle still won't stop any faster than a regular vehicle. Some people with 4x4 will drive faster because of all the traction, but when they do lose it, it is too late. If you drive normally, you have a better chance of getting there. I remember driving with a young kid in Quebec. He was driving a car with studded tires, he was driving like a maniac, I asked him why he is driving like that and he replied with " I have studded tire, I can."
One other thing I learned too is if you are sliding straight with the front tires turned in a 4x4 if you press the throttle a bit, the front tires will grab and take you where you want to go.
