Good. Really dangerous when you get huge sheets of snow/ice flying off a tractor-trailer.

A pet peeve of mine. It only takes a few minutes to brush all the snow off the roof. I always start the car right away and turn on front and rear defrosters so by time I am done, everything is nicely warmed up inside.

Not sure how the tractor-trailers get the snow off their rooftops however.
