Anyone else notice the broken seat? You could see as the car rolled over the seat broke and the drivers body was flung to the middle of the car. Pause the video at exactly minute 4:00 and you can see the drivers leg and foot are above the steering wheel, with his head in the passenger seat! With the seat braking it forces the drivers hands off the steering wheel and they are flying around in the cab. At one point it looked as if his hand and arm had come out the roof. One more reason with video proof that the standard passenger 3 point seat belts do not work in an off-road vehicle. If the seat would have broke and if the car had 4 or 5 point harnesses, it would have kept the driver still in the drivers area in the car.
Then when they showed the rear of the car once up-righted the cage looked to be pushed over to the right (Passenger side). Two things I questioned when I saw the car at the Sand Show was the lack of tubing behind the seat. So before you could add 4 point harnesses, you will need to add a tube across the rear of the cage. Then I see ZERO triangulation in the cage. They need a diagonal tube, X or V behind the seats. If they did I would bet the cage would not have bent over, or at least not as far as it did.
Then to see a suspension link bent on top of all that. It would not have been so surprising if that was all that happened, but having that seat come loose or brake is a huge red flag.
