> You're ignoring a reality where a culture has _figured out on their own_ an optimal way to navigate from point A to B in bad traffic, (mostly) safely while constraining themselves to the _intent_ of the law, if not the letter.

This is self evidently not true though. Humans are terrible drivers, and the road would be safer if all of those people who are unsafely not following the rules instead followed them.

The reality of the world that we live in is one of terrible drivers that get into lots of accidents.
