The people of California voted for it (through their representatives).
They’re free to change it at any time.
It’s not the federal government’s job to mess with it just because it doesn’t align with head-in-the-sand worldview on electric vehicles.
California didn’t mandate anything for any other state. The fact the automakers don’t want to bother to implement “the winning strategy” for every other state of pretending EVs suck either indicates it’s a terrible strategy or they think there is a benefit to their bottom line to follow demand.
The representatives of the people of California make many inane and destructive decisions, of which this is one. Once the consequences start to bite, they may come to regret it, and I hope they do.
