If we could detect these are part of bigger road relations, we could bring the missing pieces (that aren't motorways) earlier?

Yeah, I think highway relations are the only way to solve this, because right now it's using a naive interpretation of highway=motorway to generalize. A approach similar to what we're doing with minAdminLevel in the boundaries layer could work.

The ref tag in OSM can also help maybe. At least would for A2 which turns from highway=motorway to highway=trunk in the Gotthard tunnel in Switzerland... https://maps.protomaps.com/#map=9.47/46.6034/8.6464&theme=light&renderer=maplibregl&tiles=https://build.protomaps.com/20240131.pmtiles
