Source of global warming and deafness found in Saigon

Saigon buses are awful and need to be replaced by natural gas buses,
preferably smaller and without the fog horn. These are one of the main
causes for the awful traffic as well since the streets are either too
narrow or under construction- and often both. They honk often and when
they do people regularly combust on the spot out of shock, if they
hear it, which is unlikely because most have hearing problems from the
noise pollution. Honest.
