So I watch a lot of auto industry news and from their point of view and everything that has happened has made perfect sense. They react to the demands from the government in power. They got a mandate from Biden to go EV so they invested heavily into retooling and dropping their ICE programs. They were not going to piss off whoever was in power, especially not the Democrats so they did it.
When Trump took over, he scrapped so many of these programs and the companies were forced to take massive writeoffs in their investments. Those executives that championed these moves to EVs are persona non grata now in the industry(at least for the time being). These back and forth demands is really causing a lot of trouble for the legacy makers.
Tesla managing to be able to detach themselves from having to answer to wallstreet and not actually caring about what the government says has allowed them to go at their own pace. The other American EV companies are on life support and the Chinese companies have always answered to one entity: the CCP.
