These people are both a bit d*ckish... the question is, which is worse? Every site I've seen post the video says it's the "road raging a**hole."
But in my opinion, it's the person doing the filming. The one who is refusing to get over to let the faster moving car pass them (that's illegal in some places, and obnoxious in all places), who is also videoing while driving.
What I Do, Job-wise: So. Much. Other than playing on-air every day (and on DO YOU HATE IT? Sunday nights), you might get an e-mail response from me if you write in asking to know the name of a song or whether we're looking for interns. I'm all over the place, like a ninja, but less stealthy.
