Absolutely - I ride a "push bike" to work for at least half of my commutes. And for those of us on bicycles, the "local smog" element of the motorcycle is disturbing, since we are breathing in everything they are putting out. When even a fairly modern motorcycle or scooter goes by, the amount of pollutants coming out of the tailpipe is clearly more than a car, based upon the nose & lung test.
It's a shame that his motorcycle most likely puts out more emissions than that SUV.
"Are motorcycles a less-polluting alternative to cars? No, in fact, motorcycles produce more harmful emissions per mile than a car or even a large SUV. The current federal motorcycle standard for hydrocarbon emissions is about 90 times the hydrocarbon standard for today's passenger cars."
Dinosaurs aren't extinct. They've just learned to hide in the trees.
