I was in Saigon (Ho Chi Minh City) about 4 years ago on business. It is insane. We were being driven in a van by a member of the "Chamber of Commerce" or whatever, and they literally plowed through people on motorcycles at intersections. Bikers were bumping off the van at slow speeds and carving in and out of the lanes at higher speeds. Your typical auto lane had 3-4 bikes across and there was not a bike length between them in the forward direction. Everyone rode a little chinese 250cc or scooter and most bikes were being ridden 2-up , many were even 3-up with the 3rd person facing backwards and holding boxes, lumber or even plate glass. It was total chaos at every intersection with swarms of bikes creating gridlock at every stop.
The woman who was hosting our visit said that 20 years ago, the roads had 1% cars, 5% motorcycles, 60% bicycles and 34% pedestrians. Today it is 10% cars, 70% motorcycles, 15% bicycles and 5% pedestrians. It's almost like everyone who walked or pedaled a bike has now moved up to a car or motorcycle. Without any training in how to ride, and no real police presence, it was a scene from Mad Max.
If they are trying to snare bikers in nets, it must be outside the main city. In the urban section, a typical fishing net would gather up 20 bikes and 44 bodies in one good toss!
