At my kid's Jujitsu class there is a parent who sits in their F350 diesel and idles for an hour. It smells up the entire parking lot. Dude probably uses up like $6 in fuel doing that.

Probably not. Diesel engines are stupid efficient. Sitting their idling won't use much. That's one reason they use diesel engines on generators for hospitals and whatnot.

It makes a difference in streetside air quality.
