Two stroke scooters, yes pretty damn dirty - but there are only a couple street legal two strokes being sold in the U.S. today.
The four strokes are cleaner - perhaps not with the same types of requirements as cars, but still at 80 mpg or more they aren't a terrible alternative to one p erson driving around in an SUV. FWIW, my two stroke had a caty converter on it when I bought it. I don't ride it so much anymore - on my bike insteadk.
