This is interesting. I've given the concept some speculation before, and it seems to me that people move in the direction of their dominant hand: I say this because 99% of the time I run into someone, they go right and I go left (I'm left handed) and we remain stuck in each other's way, but once in a while I'll find someone who also moves to their left, clearing the way. As I said, speculation on my part, but it wouldn't surprise me if it were true.
