I was driving last evening and at a very busy intersection the traffic lights were out and in all directions including the turning arrows, flashing amber.
I was amazed, not chaos, intuitive flow.
Hundreds of cars began to emulate the standard cycle for that intersection – time for ongoing traffic on one highway, time for traffic on the other highway and time for the turning traffic from one highway to another. All is an ease of movement, unguided by the turning of lights from green to red and vice-versa, just doing it as if – even as an ambulance with flashing lights insisted on doing a u-turn on one of the highways.
It was truly a miracle of co-operation to be part of.
