I have been to a few Countries in Asia (Taiwan, Thailand, Philippines, and now Vietnam), and the general mode of transportation is a scooter. I am blown away by the traffic flow each time and always explain it as ants marching.
Everyone gives way to the other all while getting to their destination, fast.
If you took the time to watch any of the videos, you would notice that almost everyone smiles and says hello to me. That is the first thing I notice in a new Country, so I know how much I can use my charming personality to have more fun.
