I have seen this, or something close to it, on The Travel Channel I think when they discussed theme parks. They have the same robotic arms with 3 or more arms for multiple people. Looks really dang fun in my opinion, but no way would I ride on that one with the current program. It had his head insanely close to the ground, and his feet frequently touched the ground. I absolutely love roller coasters, even this one, but that would scare the crap out of me to watch and then do...
