I still don't see what's the problem. Assuming that the time a car motor
is switched on is constant, it is better burning fuel while idling
instead of burning fuel while driving.
Pleae take into account that the traveling *time* is the long term
constant, not the distance.
If you substitute 'idling' with 'driving slow' your statement would be:
"40% of pollutions are from traffic driving slow" and "if everyone goes
faster, we have less pollution". That doesn't make sense.
