they also walk over each others bodies, and yield to others with grace.
Translate this to vehicles, and this means unspeakable chaos, collisions as an intentional operation, and unheard of courtesy.
And yet an insect with a brain smaller than a grain of sand can somehow figure it out while humans with a brain thousands of times bigger and more complex can't find a way to make it work when it comes to transport routes. Thinking about it further, perhaps it is because ants 'have to' obey the 'rules of the road' while humans have free agency which introduces an (almost?) impossible to optimise for degree of chaos. In other words it is unlikely that a single ant would disrupt the flow of traffic whilst a single human could (and often do) manage to obstruct routes through a misplaced sense of their needs/wants outweighing the needs of their fellow 'commuters'. Guess ants figure that things work best with universal co-operation whilst humans appear to optimise for a 'me-first' outcome. It will be interesting to see which option mother nature/evolution decides works best.
