You guys made me think of a coaster where the trains are really powered by an engine; not electrical but good old internal combustion.
Imagine sitting on a launch track and instead of a cable pulling you you feel the vibrations of a 350 HP-engine, smelling burned fuel and hear the deep howling of a Shelby GT......
Would definitely be awesome

When I was GP I encouraged myself to go on Superwirbel at Holiday Park for the first time by saying "Don??????t be afraid, it just HAS to be save...it??????s checked by the "T?????V" (an organisation in Germany to check any mechanical devices that are meant to move people or goods. Any amusement attraction, car, train, elevator, plane,(...) used in Germany has to get their seal to be allowed to be used.)
