Video: A row between a biker and a car. Then a kick, a car comeback and it gets real crazy, real quick

A caught-on-camera road rage incident between a motorcyclist and a driver on a freeway in Santa Clarita led to a chain reaction crash, sending an innocent person to the hospital Wednesday, authorities said.

The crash occurred before 6am, today, on the southbound 14 Freeway near Newhall in the USA. The passenger who shot the video said he started recording when a grey car inadvertently cut off a passing motorcyclist.
