I do tend to apply this same idea to a lot of things I buy. If there's an American version available with at least similar quality and some % of similar price, I'll pick the US one nearly every time. Goes even further when its something I know is made in my state, even further when it comes to the city I live in. The vast majority of the beer I drink is made in the city I live in, for example.
And in the end that "$10k" Chinese car doesn't fit my needs in the same way a $14k US or Japanese car doesn't fit my needs. When I actually look at a vehicle that does do what I'm looking for, they're not too differently priced.
Note that the "$10k" car in China costs ~$22k in Mexico. So chances are, even without tariffs that car coming to the US would probably be $20k+, not $10k. Probably more, because BYD knows Americans would probably pay more in the end. That's without any tariffs applied.
Chances are though, a similar car to what I'd buy would be more along the lines of the BYD Seal, but even then that's a little smaller than what I'd like. Honestly the Mach E is pretty much the perfect sized vehicle for my family for the majority of our drives, so something like a large hatchback/small crossover is what I'm looking for but a full-sized sedan would do. That went on sale in Mexico without tariffs for 888,800 Mexican Pesos, or about $44k USD. A The 2025 Mach E pricing starts around $37k.
edit: presumably you don't (or can't) hold this position for electronics or a myriad of other devices you already own. Why are cars different?
