Idling equals getting ZERO miles to the gallon. It wastes money and petro, damages modern car engines, and creates pollution. Each day Americans waste 3.8 million gallons of gas and 40,000 tons of carbon dioxide by voluntarily idling their cars. Voluntarily idling can also damage a car. It is better to turn the car off and back on, even if it is for just 20 seconds while you are at the drive-through or car-pool.
