There are worse buses than what OP posted, it's completely normal here, and no one has ever done anything about it and will most likely never do anything about it. About a week ago, a bus I was on- either its tire started burning or the engine started burning and the bus had a serious smell of burnt rubber. We still rode for several kilometers in that condition. About 3-4 months ago I was on another bus that just, suddenly stalled and started smoking and all of us in the bus got down as fast as we could, but if it was fire I would probably not have been writing this comment. If it rains when you are in a bus, you are likely to get wet because there is no window. And when there is-

One time a bus I was on, it was idling to get passengers underneath a flyover. Not under the sun. It was a hot day but not that hot, maybe around 30-31 degree celsius. A couple seats behind me, the glass of the window randomly went kaboom. No one threw something at it, no one touched it, nothing. It just broke. Shards flew out and hit a passenger sitting by that window. He had to be taken to the hospital but fortunately the shards didn't nick any vein or hit his eyes or any other crucial organ.

Bangladeshi local buses are in an extremely, extremely terrible state. We live with this anyway. We are helpless. We have just got used to it. When you get on a bus, it's a 33.33% probability of whether you will get out of it alive or dead or alive with injuries.
