In many Northern and Western European countries highway junctions have both numbers and names. They are usually quite long, like "101 Trafikplats Huskvarna Norra" (Sweden).
When in Navigation mode, Google Maps shows them in huge yellow rectangles on top of everything else! It obstructs the most important elements of the map — lanes, turns and intersections themselves.
Above is an example where I can't really understand where to go, but I can clearly see the absolutely non-important thing: the name of the junction. It doesn't make any sense. It takes a single real-world test to realize that this feature is bad.
