Not sure if you are aware of it, but in Singapore, those pedestrian traffic light with the button on the pole, will remain red until the cow comes home, if no one presses the button.
So it's an interesting social phenomenon. People furthest away from the pole assume that someone nearer to the pole would have pressed the button, and/or are too lazy to check if someone has pressed it (a red light lights up beside the button if it has been pressed). While those nearer to the pole just don't know that they have to press the button. A lot of assumptions, a lot of ignorances.
I wonder if you can plot a graph with x-axis denoting distance from the pole, and draw some conclusion.
