With some exceptions, there’s going to be a point where a used car is not worth the trouble to ship it somewhere.
And Americans love their huge ass cars. I can’t see many cheaper markets wanting to use an American car, just for the fuel cost alone.
I bet the cars get trashed for scrap or parts.
Absolutely it does. If you live near the Mexican border of the US, it’s extremely common to see older cars being towed headed south, presumably to Mexico. It’s not particularly expensive to drive them down to the border.

Only the least valuable and oldest ones that other countries don’t work. That means you’re overall moving up the modernness of the fleet. Presumably with better fuel economy, lower emissions, and fewer problems.
Also to Belize and other parts of Central and South America. They don't all stop in Mexico.
