11 people have been injured in this road rage incident that happened in Istanbul Turkey.
From Live Leak:
Already angry before the bus had set off, the passenger returned to the front of the bus while it was in motion and assaulted the driver with his umbrella. He lost control of the vehicle, which then ploughed over oncoming cars on the other side of the road before crashing into another bus.
Local media reports say the initial argument had been about opening the doors. Passengers restrained the angry traveler after the crash until police took him into custody.
