Also, does anyone know how the vehicles rotate?
On X2 at Six Flags Magic Mountain, the "pods" rotate based upon a single side bar piece on the the track. This track piece would move up and down depending on the desired motion the engineers wanted the "pods" to rotate in. On the Guardians track, there is no additional side bar or visible piece to rotate the vehicle. So does that mean that the cars rotate based on like a computer system and sensors that tell the axis when to spin? I mean X2 was build 20 years ago and technology has advanced a lot since then, so thats probably true.
Here is a picture of of the 4th dimension coaster (X2) track for reference-
