That there are such things as emissions requirements. There are laws that say that vehicles can only produce a cetain amount of emissions.
SUV's fall under those laws. In fact, they have a lot more equipment on them to make sure that they emit proportionately less than a smaller engine would.
So, in reality, all those people who drive small cars are hurting the environment just as much since they don't have all the equipment to reduce emissions built in. They don't emit as much pollution as a big car, but they emit proportionately more.
So I think we can safely say that only some Americans are idiots...like those who put up posts like this.
