We don't know what he did before he started the video, but if you watch him at about 4 minutes in, listen to the engine and just watch the RPM clusters he's reving it out, engine braking on the limiter almost and commenting that he hasn't figures out where to shit the truck.
I just noticed that.
Honestly the more closely I look at that video the more obvious it is that the whole thing was a setup ... no one can be that shitty a driver. He's bitching about wiper blades while pegging the limiter and wondering what happened when it kicks in to save itself from him.
