The factor that causes the rollover is the driver side tire being forced under the vehicle. Slow the video down to .25 speed and you can watch it compress under the frame and then pogo the jeep up on two wheels. Ford addressed this on the Bronco with the crash bars. I'm surprised it's such a difficult thing for Jeep to suss out. Further, I wonder if a solid set of frame mounted sliders would be enough to act as a impromptu crash bar.
