I live in CA as well, and it's BS that we can't get new VW TDI's or MB CDI's that get high mpg here, yet people can drive their Hummer H2's and get 9 mpg. Seems like it's the big rigs that are the bigger polluters, not the passenger cars... i dont see big clouds of black smoke coming out from even our 20 year old Benzes, of which i see a lot of actually.
