We all know that an idling car gets 0 MPG, but how much time is alright?
10 seconds, it turns out. After that, an idling car wastes more fuel than a full startup would consume. In today's modern fuel-injected engines, starting a warm engine is nothing.
Perhaps you're concerned that continually shutting off and restarting the vehicle is hard on the engine. But studies show that frequent restarting has little impact on engine parts such as the battery and starter motor. The wear on components that restarting the engine causes adds about $10 a year to the cost of driving – money that you'll likely recover several times over in fuel savings from reduced idling.
Excessive idling could also lead to engine damage. Idling doesn't fully burn the fuel, and the leftover residue mixes with oil and sticks to engine parts.

So who is going to change their driving habits?
