US automakers urge Congress to quickly pass law banning Chinese cars

What is stopping someone from flying to mexico, buying an EV there, and driving it back and getting it registered?
Some states may have safety regs, but some mid-america states don't seem to give a shit about what you drive where.

Registration. If they haven’t gone through all the National Highway Safety Administration tests, it’s not able to be registered (or was a while ago, I haven’t kept up). A couple of decades ago, there was a billionaire who bought a couple extra supercars and had them destroyed by testing, so that his would be road-legal.
