In a culture, there is little to gain by doing things differently from how everybody is doing things. When everyone is violating traffic rules, the most optimal course of action is to violate traffic rules. This is exactly how a Nash equilibrium behaves.
Cultures can be changed, like how Nash Equilibria are broken:
- With great personal cost to the change agent: Gandhi, Martin Luther King, Jesus.
- With great personal cost to all members of the culture: Totalitarian systems, Extensive regulatory framework, rules and laws (traffic laws) which restrict liberty.
All Nash Equilibria of a game cannot be enumerated before they are created because that is an intractable problem.
