Ho Chi Minh City, Vietnam
Crazy massive junction in Saigon. More motorbikes than I've ever seen in one place bar organised bike rallies. We sat having a coffee and watching this for a while and could work out no system to the traffic- they all just come from all angles and merge together. We've been told that to cross the road you just walk out into it and walk at a slow and constant speed and the bikes will dodge you. It's pretty scary but seems to work!
