Bikes in Ho Chi Minh City demonstrating fluid flow

Its quite mesmerising (to someone who hasn’t seen it before – like me) to watch busy intersections in Ho Chi Minh city and to observe the ballet vehicles and people crossing each others paths without a crash to be seen.

Here are a couple of short video clips that hopefully demonstrate this effect at least partially. Seeing it in real life is even more impressive – perhaps because of the sheer panorama that your own eyes can take in, and that a camera field of view cannot.

Here is a cleaner sweeping the intersection as vehicles pass around him.

Here is some more footage of all sorts of vehicles passing through each other at various angles without any apparent collisions.
