And how does that make the exhaust gas more polluting? You still haven't explained that!

More air means more exhaust. Duh, of course!!! So does more driving. I still don't see the point.

If, say, 20% of the exhaust are emissions, if you put more air in, you'll get more exhaust, but still, only 20% of that will be emissions. So how is that worse?

Smog measures the percentage of pollutants in the exhaust gas and so far nobody has shown that more air in the engine increases the percentage of pollutants. You've only said that more air in equals more exhaust, to which I say: DUH!
