If someone knows how to create invisible routeable ways, then we might consider hiding underground roads.
You can do so, but only by using a TYP file. Take some random type from 0x01-0x13 and make it invisible by assigning both colors to transparent.
With the current state of mkgmap I see no way to create invisible roads. But from technical view it should be possible. Simply add the way to the routing tables, but not to the line drawing tables. Nevertheless needs some refactoring before being able doing this.
If that is possible, it would be better than my above approach.
While thinking about it, I think a found at least a workaround: What happens, if you assign this type of way only to the resolution level 1 (the least detailed level) and NOT to finer resolution levels? It will never be displayed at any zoom level! (Lowest reasonable zoom needs at least resolution 8)
Routing has to be in resolution 24 to work well, so I don't think the above could work.
This is possible with current mkgmap.
