Thinking government can help is wrong to begin with. It can't, it can only get in the way. Perhaps electric vehicles and definitely smaller vehicles could've been more prevalent today without the CAFE rules. Other environmental rules prevent (or make prohibitively expensive, same thing) the mines in which rare earth metals for batteries for EVs are produced.

At least the federal EV mandates are gone now (my state's still exists though, sadly). That would've only driven up costs, meaning more people either would NOT drive EVs at all, or would be even more in debt then they are now.
