Ahh, but sometimes the weather overtakes one on the road. Two Februarys ago, we were returning from Las Vegas, and mid afternoon, 50 miles from Susanville, we hit an unexpected storm. By the time we got to town where we could hold up, we were on 4+ inches of snow.
Sometimes its difficult to plan around that kind of problem.
A close friend was maybe driving tooooo slow on packed snow. On a supered corner, his whole rig, truck and fiver slid off the road on the down slope---and down a 20 foot embankment. Often wondered whether a bit more speed would have kept him up on the road??
