No, I got it. It was other people blocking off the passing lane, slowing the flow of traffic, causing traffic to back up, and creating road rage. You were nearly the victim of that bad situation, a situation that was created by someone up ahead blocking the passing lane, and exacerbated by a hyper-aggressive asshole in a big truck. If traffic were flowing smoothly, and the left lane was moving faster than the right lanes, as it was designed to do, then H-AA in the big truck would have been in the far left lane, staying in his lane, moving past you safely.
When you see a traffic jam for "no reason", no wreck or road work or anything, it was generally caused by people blocking passing traffic in the left hand lane. That's what creates these situations on interstates that become extremely dangerous for people back in the line.
