Which is greener: Car vs. Scooter

Which is better for the environment: driving a car or riding a scooter? The argument still rages. O.K., not so much rages, but irritates… like a piece of fiberglass in your skin. Cars have better emission controls, scooters use less resources. This article tries to explain the difference. I note that he is comparing a 2-stroke scooter. Replace that with a 4-stroke and the scooter comes out further ahead.
