Doubtful it's fake. I've seen a video of some guy going to town on a car with a tire iron on the strip, midday, in traffic. Nobody did anything in that circumstance.

Also, I think the original video is shot outside of a bar, Pinkie's, and behind a gas station. Both off of Flamingo Road. One of the more busier streets in Vegas.
