It is not preventing someone else from making that same standard like "only if you build your cars in CA you can sell it here or tariff". Detroit is building cars for CARB standard and sell a lot of them here with no extra tariff vs cars build elsewhere.https://www.latimes.com/environment...n-bid-to-overturn-california-gas-only-car-ban
How is this CARB mandate NOT the "regulating of interstate commerce"? Effectively CA is blocking a Detroit company (say Ford, GM) from selling their cars across state lines? When CA announced this, I immediately thought this wouldn't be constitutional and "interstate commerce" clause. Lets not forget when this clean air business started. This isn't 1969, even my camaro is "CA Compliant." Under the auspicies of clean air and CARB, we've seen CA tank the oil industry in this state to the point where our gas prices are nearly double everywhere else in the country. Enough is enough.
My uncle visited from Wisconsin for the first time since 1988. He could believe how clear the air was in comparison.
Oh and by the way, my cost to charge an electric car is 30 cents a kWh at home at 3 am, 50-70 at a supercharger. Its not about "smog" or the environment; its a racket.
The problem is cost and economy of scale. The justification is without California the Fed standard can't hit economy of scale in manufacturing all by itself, so they want to remove that.
Air quality can have a lot to do with density and local climate. In Central Valley air can stay trapped and turn into smog with the sunlight whereas in mid west gets blown away and the corn field just absorb them before smog form.
