I did two years driving a transit van through some bad winters , and they are hopeless on snow , but with a bit of skill , and a handy shovel , i did not get stranded...
I learned about snow driving in the army in Germany. I remember one year in England driving down the road in my creaky old Ford Escort estate, pulling people out of ditches and snow-drifts. I ended up giving a lift to a one-legged mountaineer who was riding through the blizzard on a Honda 70 step-thru.
