Regardless of where you stand on EVs, it's the lack of consistency in US regulations and policies that is infuriating. Personally, I have no problem with tax incentives to encourage people to buy electric cars. For folks whose situations are such that an EV of the current generation would be a good idea, this can help get them into a type of vehicle that, arguably, can be better for the environment than an ICE choice. And while not ideal, I would not have severe problems, conceptually, with letting the market decide, and leave the incentives up to manufacturers. What I find infuriating is the stupidity of not actually having a national policy of any sort, and being inconsistent. Keeping potential buyers in limbo, no knowing whether the incentives will be there when they want to buy, is dumb. Keeping manufacturers uneasy about how viable making and selling these cars might be is even dumber.
If I was a stockholder in manufacturers of EVs, I'd be kicking up a fuss and insisting the federal government get its shit together. But then, we know that ain't gonna happen no matter who is in power.
