These places have a lot of people. No matter what we do there will always be place where there are more people than others. imagine yourself in one of those trains in the video. All the people pushing you around, getting squished against all the other people, and not being able to control your own body. There is only one way you could get me on that train and that would be by force Which it looks like that's what their doing.

  Most of the people don't like being on the trains and getting pushed around. The whole lot of them don't have much of a choice though. The traffic in cars would be even worse. Would you live there?
