...this should be over ruled by the US Congress using the commerce clause because it will affect the price of cars for me up in Washington State even though I can't vote against Davis.

Interesting proposal. There is legal justification for it, too. From The Fed’s Depression and the Birth of the New Deal

In 1942..."Ohio dairy farmer Roscoe Filburn was prosecuted successfully by the compassionate federal government for violating the Agricultural Adjustment Act by growing grain for his family’s direct use. In a unanimous decision, the now-tamed Supreme Court ruled that Filburn had engaged in interstate commerce by not engaging in it. Filburn, the Court ruled, should have purchased the grain with which he fed his cows, chickens, and family, not raised it himself. In order to permit the federal government a wide range of action, New Dealers destroyed the doctrine of enumerated powers."

It is my understanding that the legitimate use of the Commerce Clause allows congress to pass laws overruling State's laws whose effect is to unduly interfere with interstate commerce. This law because its affects go beyond California can legitimately be overruled without stepping on legitimate State's rights. This act will raise the price of and change the engines of cars sold across the country not just those sold in California.
