How did these people survive?

I have no clue how they survived this. The truck lands on top of so many people. It would suck to be the person hanging out of the back window. She is just going along from the entire ride. If I was in the bed of the truck and it was swerving like that, I would definitely think about jumping out before something serious happend. In this case something serious did happen.

If the driver survived the flip, which it looks like they did, I would rally the troops and beat there ass for driving like a dick when the who town is in the bed of his truck!
