As you turn on your car’s engine and wait for your mom or sister to finish putting on make-up, you wonder if you’re wasting your gas while warming up your car.
You get caught in this dilemma whether you should just shut off the engine or let it run along with the air conditioner so you can save on gas. This process is called idling.
Idling is when the engine is running, but the car is not in motion. One example of idling is when your car is waiting at a traffic light.
