Ho Chi Minh City (formally Saigon) is one of the fastest growing metropolitan centers in Southeast Asia. Home to roughly 9 million people, the streets of the former French colony have grown increasingly chaotic, to put it mildly. But this timelapse short film from photography Rob Whitworth depicts the throngs of traffic as the essential lifeblood of the city. Pulsing with a consistent rhythm, the ebb and flow of the vehicles is how the city keeps its beat. What I can’t help thinking about is: what if all those motorbikes were cars? Or conversely, what if all the cars on the packed Los Angeles freeways were motorbikes? Imagine the horror.
