I think it is a great design, that if it is placed in any park would be real popular. Imagine traveling along a regular coaster track and than coming to a stop, and then the coaster track itself actually starts moving than the next thing you know you are facing straight down towards the ground, and then all of a sudden release and you are free falling. I think people are underestimating the sensation of a moving rollercoaster track and how unnerving that would be. I forsee a rollercoaster where not only the train moves but so does the track throughout the entire length of it.
