... Are you stupid? A free market allows for ANY competitors regardless of how the company is run or its location. By banning an entire countries products you are making the market less free for the buyer by lowering the competition for American cars.
And let's be honest US cars suck dick. I'm driving a fucking Dodge Laramie and its a piece of shit, the tech is all over the place with no normalized menus and and annoying as fuck central IPad for a dash.
