When i came in the U.S.A, i was suprised. Because all american use big cars and big engine. Every country has a problem with gas. Also U.S.A has problem with same situation. I don't understand why they use big engine cars. If u don't have speed limit strongly, you can use your car engine everywhere. But it is not possible in the U.S.A. Especially california's police is really strict about that. If you know this reason, you should comment my blog.
