Thanks but not thanks, most people on the public transport are disgusting and weird... Although I can live with that, they would need to have 24/7 schedules and insecurity is a big downside too.
Disclaimer, I actually don't know if trains work 24/7 as there is not a single one where I live (not for passengers at least) and even if there was insecurity still an issue, one of the disadvantages of living in a 3rd world country.
