Apparently I just live in a place where it's not a common problem. Also I do tend to leave a big gap behind cars in front.

They salt your roads, or put grit?

They don't do either of those things, and yet somehow I haven't witnessed any cars sliding off the road in winter either.

From everything you've said so far, it sounds like people in your area have a lot of sense.

Also we don't get snow.
