Shibuya Crossing
This may be most famous and busiest crosswalk in Japan.
All the traffic lights turn from red to green and the pedestrian lights turn from red to green at the same time, all the pedestrians start walking in every direction simultaneously. After only 30 seconds (or so) of the pedestrian light being red, a big crowd of people have already gathered at each of the 6 sides of the crossing.... You might think this would be chaos. But No ... at this miracle crossing, everyone gets where they are heading.
This picture taken on a weekday afternoon. On weekends, the crowd are triple the size.
