This would only be an issue if the difference between two "adjacent" classes would be so big that you would jump from "almost none" to "to many to display" in one step. > lane and surface data is also almost > certainly not helpful here even with full > coverage > And it would result in weird transitions > between countries. Only if road density changes rapidly at the border, and then we would just depict the weird transition that exists in reality. I think it might be possible to upgrade the "minimum zoom level to display" on a way if there are no already displayed ways in an area, maybe only if it connects to an already displayed way (recursive). That way we would boost the minimum zoom level of e.g. https://www.openstreetmap.org/way/196509120 to zoom-level 11 or maybe even 9, even with it being just a low quality dirt track going near an obscure archaeological site in the middle of nowhere.
