There should be no EV mandate, then there would not need to be consumer protections as the market would do what is does best and allow manufacturers to compete on the merits of the vehicles not by the government choosing what we should be allowed to drive.
I think there are already too many regulations on the manufacture of cars.
At the state level I think the only regulations should be those around direct safety concerns (like air bags, lights, etc). Efficiency or other non-safety related regulations should be disallowed. Further safety regulations should be limited safe operations for other drivers sharing the road, not passenger protection (outside of regulations on truth in advertising, product defect)... passenger protection should be a market dynamic, coupled with greater tort reform to be able to hold liable manufacturers for their marketing claims.
This is why I'm really skeptical of mandating EVs without consumer protection because this seems to be the point where automakers are seeing dollar signs and can force buyers into higher price brackets.
