Well, whether it was real or not, I liked it
One time, while on a double date in high school, we saw some baggage fall off of a dodge 15 passenger van. As we were travelling on a 2 lane highway, we had the opportunity to try to signal the driver and let them know they'd lost a bag from the roof rack...
Bad idea - the asshole decided that we were worthy of a road rage tantrum and he followed us in to the small town we were going to visit on our date, honking, trying to force us off the road, and making obscene gestures the whole time. We tried pulling over, slowing down, speeding up... he never tried rolling down his window so we could talk to him... He finally left when we pulled into a strangers driveway - wierd.
I find this scenario to be plausible, but this particular case is highly incredible. It's very convenient that the camera catches all of the action... like bubba picking up a baseball bat instead of watching the yuppie get out of his car. Oh well, I hope they had fun filming it.
