You'll never use a frying pan at the wheel, true, but keeping a can of cooking spray in your car is still a good idea—especially in winter. If the forecast looks bleak, pull out the spray, then open all your car doors. Spray the rubber seals along the edge of the door, making sure to give each one a good coating. The oil will prevent melting snow from sticking to the seal, so you won't have to play tug-of-war with a door that has frozen shut overnight.
