Soviet road and rail maps of the USA were more accurate than the USAs.

  It's one of those almost paradoxical things - the maps by the people who use a system can be very incomplete - because the system is right there! You don't need a detailed map of where the rail line between two points is because you can just follow it. Another example is blueprints - they seem very detailed and accurate until you realize that quite a bit is "left out" and the tradesmen are assumed able to figure it out - it will show fixture locations for example, but rarely show exactly how the wires are run to them. But if you're creating a 'map' of a house you bought, wire locations is extremely useful because they're all behind the walls.
