#337: Exhaust smell in foreign countries

Living in a country with good motor vehicle emission standards, you forget the much of the world doesn't have the standard of living to enforce these rules. Even in a fairly well-off country like Argentina, I became annoyed at smelling exhaust, even in the smallest of towns in Patagonia. It just took one idling pickup or bus to stink up the whole area in a wide radius. Also, to make matters worse, they leave vehicles idling a lot. I think it might be due to being scared that it won't start up again if they shut it down while waiting to drive off. Severity: 4
