Diesel idling limits are targeted at commercial vehicles. Plenty of truckers are in the habit of idling their trucks, large or small, whenever they stop. The combined emissions are significant. California just passed an idling restriction and figured it would prevent several thousand tons of exhaust emmissions annually, along with many millions of dollars in lost fuel. Truckers supported the rule, because it saves them money and repair costs in the long run.
