An obvious measure of Saigon's change is the car to moped ratio on the city streets. I'm not talking about the luxury editions from Japan and Europe, just regular automobiles. More and more Saigonese can afford them but the city streets cannot; most were never built to accommodate the volume of traffic they get today.
I can't wait to see how the city has changed since 2006. Will I be devoured by mopeds as always, or will my taxi from the airport have to yield to Maseratis, Mercedes, and Rolls Royces? Can't wait to see.
