Your comment reminds me of the hostile, to say the least, Munich U-Bahn map:

I remember seeing it back then in the subway, looking for directions and feeling really confused about it. "Damn why didn't I get a transportation systems PhD before coming to Germany!"
The concentric rings remind me of atomic bomb destruction maps where they have different rings for different damage levels.
Hostile is the PERFECT way to describe that map. You got me chucking this AM.
