16 loaded from openstreetmap.org, or any compatible service.
17 The Earth is very big, and full of Things.
19 As you ponder these maps, remember that traffic always expands to fill
21 all available lanes, every car is a policy failure, and the concept of
22 "jaywalking" was invented for profit by auto industry lobbyists in the
23 1920s.
