How would you feel if someone heaved a 3-foot-diameter, 40-pound dinner plate at your windshield? Not too swell, we're guessing. Well, that's exactly what happens when a rooftop of snow and ice on the car in front of you goes airborne. In addition to soiling your trousers, such unwelcome crash-landings have been known to shatter windshields. In some states, it's even against the law. In all states, it's a sign of thoughtlessness. Don't Be a Jerk: Take five minutes to clean the snow off your car before you drive away. You'll see better, and you won't inadvertently launch an attack on the cars behind you.
