So, no excuse for the pickup coming over on you, but from the video it appears that you got annoyed because he was following too closely. So, to teach him a lesson you slow almost to a stop on the exit ramp. I'm sure that pissed him off pretty good. Then you hot dogged it, pulling the front wheel just to show him who's the really cool one on the highway. So, thanks. You succeeded in escalating a situation and portraying a negative image of a motorcyclist. Hope the next motorcyclist he encounters doesn't get run off the road because of your example.
