I conducted a little photographic social experiment in the Montreal Metro. I call it the Law of Maximum Displacement. Strangers always space themselves as far away from each other as they can, neatly demonstrated by platform benches. I think it's really weird and bizzarre how predictable it is. A fun game is to look at these pictures and figure out the order in which the people sat. It's so predictable that in a lot of cases there is no doubt what the order for sure had to be.
