France has private-ish roads that are quite expensive. So does italy, there you have to often literally pay a human everytime you get of the highway. This leads to many people driving on small roads, polluting and wearing down those roads.

Not sure about Germany, but they just have a super strong car lobby in general, and its one of their national pride things, so they tend to find money for that.

Here in Switzerland we have a very high gas price, but that leads to many people going for gas outside of Switzerland and we have no idea what to do when EVy really take off. The true cost of those roads is hidden in the 'normality' of the high gas prices.

Roads are a tricky problem, not just for libertarians.
