Not sure what’s up with Poland turning into a frenemy
It’s not the government driving it, but truckers who don’t want competition from Ukrainian truckers.
You had similar upset about truckers from eastern parts of the EU. I remember some long-running drama when French truckers took issue with Hungarian trucking companies that didn’t conform to French minimum wage law.
This is not to excuse it – in the US, if you start blocking off public highways, I’d expect the cops to be arresting you before long – but a number of countries in Europe definitely do have some level of letting people get away with stuff like that. I remember a while back when French winemakers were stopping Spanish wine trucks – Spain had been outcompeting France in wine, moving in on their turf – and dumping wine onto the road while the French police just watched.
