Regarding different speeds on the same road I totally agree with you. But unfortunately on your second comment I must disagree. I have one of those big SUV's you mentioned, I'm western and I respect the law. The main reason I bought such a big car was for safety, I don't know if it's really safer but that's the way I feel it. And I see all the time many small cars (tidas, altimas, etc) and all kinds of nationalities driving as fast as anyone else, maybe they look slower than SUV's because they are smaller, but that's all. And having different fines based on the type of your car... cam'on, we already live in a unfair country, let's not make things worse! Cheers.
