It could be all three since racists tend to think China makes bad products and have unethical practices because they are Chinese due to conflating race and culture.
Only if it had something to do with race. If it's because you don't think their manufacturing standards are high enough to feel safe that wouldn't be racist per se.
Electric cars are so much simpler than ICEs...they're almost "phones with wheels"...so IF you happen to "trust" "buy" their phones, it's not a huge jump to cars...but it's a jump 😅 , just not on principle.
I know, maybe trust was not the right expression. The issue is that we still buy them, even if we know they're pumped full of spyware from a country that is not an ally.
