Yep. US makers will not bother if they can't sell in CA.  Foreign makers
who have a lot of experience selling passenger diesel cars in the rest
of the world will not import those into the US if they can't sell them
in CA.

Subaru was recently quoted, in regards to their new boxer diesel, that
chances of them of selling it in the US were nearly nonexistent unless
they could sell it in all 50 states.
