Time to shift gears

The dictionary meaning of the word ?idling? is ?unproductive?. Of course, this may mean different things to different people. Idling as a concept itself is anti-productive, an unsustainable, wasteful and resource-draining activity. On a micro scale for instance, fleet owners know how much fuel is wasted while the trucks are in idling mode; contractors and plant hirers know what idling of machinery means.
