Look. It's really just this simple. If you live in a place where it snows, and your car/truck/SUV/van/whatever is covered, then I don't care how late you are, or how tired you are, or how hard it is to reach. You have to get a broom or a brush and GET THE SNOW OFF YOUR WHOLE VEHICLE, AND NOT JUST A LITTLE PORTHOLE IN YOUR WINDSHIELD YOU CAN SEE OUT OF. Here, let me make it easy:
Oddly enough, I get unhappy when the snow -- or, joy of joys, a big ol' slab of ice -- flies off your car and hits my windshield or just sits like a mine in the middle of the road. Seriously. People who do this are a menace to others. Brush off your whole vehicle.
