Quote by: HelioPrime  Idle and startup are the least efficient moments in the use of an internal combustion engine (gasoline that is, diesel is more efficient at idle)
Starting up the car uses 10 seconds worth of idle wasted fuel. Idle itself is wasteful because it is wasting fuel with no gain other than powering the comfort controls inside the car. |
That has nothing whatsoever to do with the question I posed, or pollution in general, but thanks.
