CA wrote extraordinarily strict rules (maybe the Feds will call them "arbitrary and capricious" ?) that unduly penalized diesel engines. As a result, great diesel engines and often the cars that go in them, that are sold in other parts of the world, are not available in the USA.
Since CA is such a large market for cars, a car maker will usually not bother to make or import a car that they can't sell in CA.
So, I am harmed by CA's standards and have no recourse - I can't vote in CA state elections because I don't live in CA.
The BMW 320d, which is sold all over EU etc. and has better performance and better fuel economy than the Toyota Prius? CA won't allow its sale because of their regulations.
Meanwhile, up to 29% of SF Bay Area smog is from China (I found different quoted numbers ranging from 20 to 29%)... which has nothing to do with cars being driven by Americans.
