Stuff is just cheaper in China.
I highly doubt BYD could sell a car in the US for $20k.
This is because the "safety" measures focus on cars and drivers, while everyone is switching to "truck" vehicles that are less safe for pedestrians.
Yeah I see no way that happens. They have no dealer network to fall back on, so they have to either partner with someone already established, or they have to try and spin up a mobile service network like Tesla did. That costs money, and isn't going to happen while selling $20K cars.
Great Wall Motors (Haval, GWM brands) is trying to push hybrids here. China already has its own legacy manufacturers like Toyota or Volkswagen.
Or Walmart. Hell, even Costco could play well here.
But yes; in practice the US have banned Chinese EVs by a combination of subsidy policies and import taxes.
