You also need to look at it in the right orientation. You also need to know which roads connect and which roads are overpasses, etc. You also need to know which roads have a higher speed limit, more lanes, etc. You also need to know how to estimate non-linear distances, or be able to use the distance markers on the map. There is more to it then just "looking at it".

Hate to break it to you guys, but the GPS will more reliably find you an optimum route than you can find yourself. That is because the GPS "knows" more than you do: current traffic conditions, road closures, etc. I know people pooh pooh GPS directions and say "I know a faster way" but they really don't 90% of the time.
