I know of no state that controls their outbound goods, so it'd be on the countries benefiting from this to get more strict, not gonna happen.

Here in Lithuania we’re still checking cars leaving to Belarus to make sure they ain’t stolen. Random car papers checks on Poland/Lithuania border is still a thing too. Both to make sure Porsche stolen in Berlin last night don’t end up in Moscow 24 hours later.

Unfortunately it’s hard to check every boot for stolen headlights and steering wheels without border control

You havent seen Border Control: Europe by Discovery network. Border Control: Spain in particular often shows them stopping whole lorries loaded to the gills with stolen chopped up cars trying to cross to Morocco.

I mean while you invalidate my literal point, it's things leaving the EU. State<->state is quite uncommon is what my point should be.
