This brings one question to mind: with Arrows' new 4D technology, do you believe that there will be a way to use it to make a suspended possible to complete inversions?
I know that they wouldn't be freely swinging, but would there be a way to "program" the insane swinging maneuvers in at the right moments, while tone it down for inversions like a zero-g roll or verticle loop? I know it sounds far-fetched, but if a 4D can rotate the car 360 degrees, surely there would be some way to control the cars lateral movements.
All of the components (the structure, cars and chassis assembly would all need to be incredibly strong as I'm not sure the ride normal would be able to withstand all of the side to side movements.
This probably most defanitely wouldn't work in real life, but a cool concept at least:)
