I think whether America allows European vehicles on American roads is really a question for the Americans to decide, not the Europeans.

If the US wants to keep its population down and medical costs up by banning safe products, that's up to the US to decide.

If they produced something bad/dangerous, presumably - though of course they may be biased, as Americans would be regarding American products.

Reversing the nouns in a sentence doesn't magically make it the same thing, semantically or subjectively or morally.

European trucks effectively are banned in USA through tariffs.

By the end of Trump's third term the US will be isolated from almost all global trade anyways.

Why would they care what we do with our roads?

The European new headlights are illegal in US. They are superior but still illegal.

Yes, ban everything please
