I think they're forgetting the turbulence and the fact that once it touches down, there's still a 30 mph (or however fast they're moving) wind that's going to push it out of the back of the truck. If they just set it down in the bed (turned off) and started driving, it would still blow out and end up in the road. The tailgate up was the best idea, turbulence not withstanding. Funny though.
