The incredible scooter traffic we witnessed in Vietnam is infamous. One of our guidebooks rated it as an actual attraction. In a way it was mesmerizing to watch as locals weaved in and out of various lanes narrowly missing pedestrians and fellow drivers. Rather than waiting for a break in traffic (which didn't seem to exist) Ryan and I learned to keep a steady stride when crossing the street, allowing the scooters to gauge our pace and adjust their own speed accordingly. Here is a photo of the numerous scooters which accumulated at a red light and a video we shot of Ho Chi Minh City traffic in action.
The traffic was worse in Hanoi!
