The US auto industry provides over 10 million good paying, middle class jobs. It is government's job to balance the needs of one group of citizens against the needs of others. They have clearly decided that those 10 million families who would be devastated by a wholesale collapse of the US auto industry are more important than US consumers getting access to cheaper (in price) Chinese cars.
I drive an EV and would LOVE to be able to buy one of those cool, inexpensive Chinese vehicles, but I also understand our government's position. I just wish, instead of an outright ban, they would (I can't believe I'm saying this) impose tariffs on Chinese vehicles to bring them up to price parity with comparable US models. That way the competition would be on features and quality and not on an artificially lower price tag.
