Preheat the Car or Not?
When it starts getting cold out, there is nothing quite like hopping in a car that has been preheated to be all cozy and warm. For some reason, warm in a car seems to get into you more than warm in a house, so I love jumping in after preheating. When you are trying to conserve energy and be more environmentally conscious, however, preheating your car seems like it would be a bad idea.
