They nuked the federal credit. They killed grants and incentives for companies investing in producing new EVs and EV factories. Manufacturers mainly focused on meeting Tesla at the luxury end and can’t beat their price to feature ratio so they’re losing money trying to match on each sale. If they sell, because dealers will lead you to gassers for more profit. States are now charging more to register EVs than gassers to compensate for the gas tax.
GM went from saying they were all in to cancelling the Bolt after bringing it back nearly immediately after the federal credit was nixed. If they’re willing to shitcan a brand new model that fast, and eat a few billion or hundreds of millions to mitigate anticipated future losses now, smaller companies like Honda will read the writing on the wall. And they did, most are shifting strategy.
tldr: Companies are not going to invest or develop EVs with all the newly introduced risk by the current wildly unpredictable clown show of an administration.
