Crossing the street in Hanoi
Walk slowly, keep walking and never run. The traffic will flow around you.
The rule that surprises every visitor: do not wait for a gap. There will not be one.
Walk at a steady pace
Motorbikes judge where you will be in a second. If you keep a steady pace, they pass behind or in front of you.
Do not run, do not stop
Running or stepping back is what causes trouble.
Watch the cars and buses
Motorbikes flow around you. Cars and buses do not. Let them go.
