It's a weird time for politicians as far as EVs go. If the goal was really about climate change and advancing EV's, there would be no tarrifs. It seems like both parties are doing things to hurt the industry. California politicians seem to be the one exception. Not saying they are right, but they seem to be putting out real legislation.
Politicians have to balance competing priorities. Yes, advancing EV’s is a noble venture, but not at the cost of the entire US auto manufacturing industry. If China is able to dump heavily subsidized EV’s onto the market they can take over the market and set US development back.
