I was going to say the same thing. Their lane splitting is done wrong. Lane splitting in of itself isn't that bad of a thing, IMHO. Its even accepted (maybe even legal but not sure) in places like California. But, the traffic there is completely different. In San Francisco, for example, the traffic is bumper to bumper four lanes accross. And many of the highways like the Golden Gate Bridge don't have exits for miles. Those two things make it a bit safer because you don't have people switching lanes. Their speed is relatively constant and no one is switching lanes. But in the video, those guys are riding through huge pockets of highway void that many of those cars may decide to enter. At those speeds, you cannot fault a driver for any accident that were to occur.
