Somewhat related... Braess's Paradox. Take the toy example illustrating that paradox ( https://en.wikipedia.org/wiki/Braess%27s_paradox#Mathematical_approach https://en.wikipedia.org/wiki/Braess%27s_paradox#Mathematica... ) and an enlightened Google maps may do the altruistic thing of telling half of the drivers to stick on the upper route and half of the drivers to stick to the bottom route, but then some 3rd-party app will come along with the "shortcut" down the middle.
