This foreigner is bold to drive a moto in Vietnam, though Hue is much more relaxed than Saigon or even Hanoi. I remember watching traffic, looking for someone to stop but traffic just kept coming. Fortunately I'm big enough (especially with a forty pound backpack) to be viewed as an obstacle so I would remove my glasses, stop looking at approaching motos and just start crossing the street. As long as I maintained a steady pace, motos would just go around me without problem. You'll get a sense of the flow in this video but it does take some time to adjust.
In Hanoi, we met a towering Aussie who resembled a rugby player, but was terrified of the traffic. He told us that he couldn't bring himself to cross the street to enter the train station because of the endless and chaotic traffic. A little boy noticed his fear so the kid grabbed his hand and walked the 6'4" Aussie across the street, without problem. Ahhh, travel.
