Carried out from the ticket vendor/waiting room of this bus company upon the arrival of the bus, it is set up behind the tailpipe to prevent diesel exhaust from billowing into the adjacent building and disturbing the residents.
Finally, sobering: the visual side effects of long-term, continuous exposure to diesel exhaust. The ability to see the harmful effects of something only once an appropriate material is “sacrificed” to visually drive the point home. If this piece of metal were alive, it would probably be in sorry shape right now. How would your lungs compare after a day (or year) in a culture where most cars are over 20 years old?
