Since they can control the speed of the cars exactly, they could make them follow a parabolic path! You could be weightless for a few seconds! Maybe 10s or more, depending on the maximum car speed. <br><br>Thyssenkrupp need to add a "parabolic" button.,(reply>), Hmm actually about 3.5s of zero g, I think, if they match the speed of the world's fastest elevator. Still, it would be great fun.
