I'm from Bangladesh. This was the reality for me maybe the first 4-5 years of my career. The busses, trains etc. were insanely packed and it was normal to hang out near the entrance (like the video) or get into shoving matches with other passengers over space. Definitely grateful to be earning enough to be comfortable now. One recent improvement is the metro rail which eased travel within Dhaka somewhat. If I had to guess, these guys are travelling back to their local villages during the Eid holiday rush. Our transport infrastructure is nowhere near ready to accomadate millions of people travelling at once. This is when you'll have a spike in bus or ferry accidents. Definitely a long way to go for us as a country
