Speaking of tunnels, would it be technically possible to hide tunnels from the map view, while keeping them in the routing graph? This could be useful in urban areas. A few years ago, I added rules to hide unrouteable tunnels, such as highway=service,access=private, or railway tunnels (subways). A separate discussion is whether it is practically feasible to hide such tunnels from the map display in the default style. In my opinion, it would be. As long as the tunnel exists in the routing graph, it can be used for routing (typically, for cars only). Pedestrians and bicyclists or anyone who is at the street level would not be confused by seeing the map cluttered with the "bogus" road. Best regards, Marko
