On cold winter mornings, some folks will fire up their cars and leave them running for 10, 20, maybe even 30 minutes, thinking they're reducing wear and tear by letting their cars warm up gently.
well that might be some people but the majority don't want to sit in a cold car before driving to their destination; hence the idle time.
