I can just imagine a not so distant future, in which kids will wonder how that people had no moral guilt over letting their vehicles pump out poison gas while sitting still.
Ex. Eating lunch in a vehicle with the engine running.

Rather than being viewed as a quack, I'd like to think that the act of turning off the engine at a long stop light would be viewed as something commendable.

But, all to often it's the opposite, and I wouldn't doubt if gas guzzlers become collector cars because of their rarity, and gasoline vehicles become something desirable over an electric.
