Exactly. CA is such a huge market it can bully the rest of the country if they are allowed to impose their own standards
because it kills the bottom line to make 2 or more versions of a product so you make one version that can sold in all locations.
I was watching a Barrett-Jackson Car Auction being held in CA years ago. One of the Cars was being sold with the caveat that is could not legally be Registered in CA.
What does that tell you. Cars, Guns, Gasoline blends, take your pick, it’s like CA is a different Country not a State.
