There are lots and lots and lots of motorbikes/scooters in Saigon. Unlike Seoul, Saigon does not have a subway system, so motorbikes are the main mode of transportation. There are approximately 3.5 million motorbikes in Saigon and the streets are full of them, engines roaring and horns blaring at all hours of the day. The scariest thing about walking around the city is crossing the street, but after two weeks here I have learned to cross the street more confidently. The secret is to slowly walk across the street and trust that the motorbike drivers will go around you. The good thing is that the motorbikes are usually not going too fast since the roads are so congested, so if you do get hit you probably won’t get hurt too bad.
