I can see both policies you suggested working out fantastically, if followed through. Legacy American automakers would panic at first before they get to work. But, if these automakers can lobby for tariffs in the first place, why would they hobble themselves by giving these tariffs a deadline? They can simply maintain these tariffs till forever, effectively doubling the price of any car out of China. The US population is essentially a captive audience. Also, judging by America's antagonistic politics, any Party that opens the market to Chinese cars would be branded traitors & enemies of the working man and they'd likely do poorly in state and national elections.
