Looks to me like that tiny little SUV passing them triggered it, which seems rather extreme for such a small vehicle / pressure wave.
Driver appears to be asleep at the wheel - didn't tap the brakes, slow down, anything.. just kept driving as the sway multiplied. I wonder if they were even holding the steering wheel.
Not much else to gather from the vid.
If I had to pick one contributing factor, speed seems to be the primary issue. For most of the incident, the thing was just bouncing around on its own.
This is interesting to me as I just got back from a LONG trip towing a 30' w/ an LR3 (similar dimensions / weight) and had tractor trailers blow by me with a 20mph speed difference and only had a slight kick that was immediately neutralized by just driving straight. Maybe once in 20 hours of driving did I feel the need to tap the brakes just to be safe - 2 second event tops. Never left the lane markers once. I have a 6" shorter wheelbase as well.
It's also possible that the driver started correcting "backwards" and just began throwing the trailer around, like what people do when they encounter over-steer in cars.
Not everyone can get an F-350, there's definitely some darwinism going on here (behind the wheel at least)
PS - random note from my trip - does anyone else notice that the tractor trailers with the aerodynamic devices (full fairings around cab, the trailer tire air deflectors, etc) seem to push WAY harder? Makes sense, just thought it was interesting.
