Thing is it would take up to a decade for the US manufacturing to be all done in the US, Trump gave them 30 days. Canada and Mexico can still work together, so it will not take nearly as long to get the retooling done but it will still be a while. Other car manufacturers will move into Canada and mexico as the US car companies start to collapse, I could see the big 3 leaving the US and trying to work outside of the US I do however cannot see that working out to well for them.
