It's a hundred people lifting a bus in a coordinated action to help. That's something remarkable and we should have examples of it documented. As you can see, it ended on a news article about one hundred people lifting a bus in a coordinated action to help.
In many instances, the crowd will do nothing because collectively, nobody knows what needs done. Cases like this start from a core few somehow figuring out how to pierce the crowd-mind was able to get a bus lifted and someone saved.
It would be a great way to figure out how to collectively amass people like this when the need arises, and use them for constructive good.
