What amazed us in Vietnam was seeing how they use the ubiquitous 150 cc motorbike. We saw lots of families of five (mum, dad, three little kids), guys carrying 5m lengths of reinforcing steel on their shoulder, guys with cardboard boxes stacked and tied 3m high on the rear carrier, guys transporting a washing machine or drier on the back of their bike- totally amazing. And then they all drive like in the intersection video above. And they're all driving one-handed, talking on mobile or texting as they go.
