Vietnam is an incredibly busy city - It has a population of over 88 million people, try comparing that to New Zealand. We have a population of only 4.4 million! I stayed in Ho Chi Minh City where there are over 7 million people and over 6 million motorbikes and scooters. Watch the video below to see a standard round-a-bout in the city. People are supposed to drive on the right side of the road but sometimes they just drive where ever they want! Crossing the road can be extremely difficult.
