When one rider in a line of motorcycles goes tumbling down, so do the rest. This five-bike pile-up on a highway in China didn't result in any serious injuries, but it's pretty shocking to watch. Who knew so much damage could happen in such a short amount of time?
Next up, when a bus's electronic handbrake gets accidentally trigged, chaos ensues. Watch as the vehicle's driver frantically runs after the out-of-control bus while it heads straight toward a parked car... with a person sitting inside of it.
