The US is concerned about Chinese EVs taking over the market. For good reason they’re not happy bad and they’re extremely cheap. I’m no economist nor moralist so I can’t say if banning Chinese evs are the right move or not but I can understand the US wanting to try to create its own market before getting destroyed by the competitor. I don’t think it’s fair to say that speaks to the quality of the US alternatives. There’s plenty of smart people trying to put this together to create affordable domestic electric cars. Personally I applaud that and am happy that competition is getting legacy auto manufacturers to finally make some interesting cars.
There is a national security and sovereignty issue that the European countries (and others) not facing - its similar to dependence on American clouds etc.
A lot of these vehicles rely on OTA updates or are controlled through apps. This essentially means the manufacturer controls them. Imagine the consequences if half the vehicles in your country stopped working, or became unsafe? Do you really want to hand this power to a foreign country?
Ultimately China and US (and anyone else in the world for that matter) are doing the same thing - helping their domestic industry compete domestically and internationally, because they want prosperity for their country. They do it via different means - China via massive subsidies and US via bans and tariffs, but the end is the same.
If someone tries to tell you that these are somehow morally different, and one of them is the good guy and the other is the bad guy, they are pushing propaganda, knowingly or unknowingly.
