A vehicle in idle can have many negative impacts. The engine running without the vehicle moving, is not good for vehicle life. Additionally, prolonging idling can also waste fuel and have negative impacts on the environment by releasing emissions into the air. According to the US Department of Energy, if vehicle idling was eliminated in the USA, it would be like taking 5 million cars off the road! So not only is idling poor for vehicle health, but the health of the planet as well!
