Whenever competitors showed up, they laughed at them, before panicking when those upstarts starting challenging their market dominance. It happened with Japan, Korea, and now China.
So, if you feel China competes unfairly, close off your markets. Countries without a local auto industry will accept Chinese EVs readily. BYD & co. will snatch American & EU automakers' foreign markets before they come home to swallow you alive by building factories in low-cost countries like Bulgaria, Mexico, & Brazil.
Basically, the Toyota cycle will repeat itself because Western (esp. American) automakers spent hundreds of billions on share buybacks instead of R&D.
