For ages, folks have been told to allow their cars idle and warm-up before driving out. So it's no surprise many car owners go through this process every day. Most times, they even leave the engine to run while waiting for a colleague or friend to join them in the car.

Car idling might appear to be a harmless convenience but it's bad for your health, your wallet and the environment. The environmental protection agency states engine idling causes global warming and has been linked to asthma, cardiac disease, decreased lung function and cancer.
