The dude walking in front of the truck and a dude at the rear of the truck are actually controlling the axles via remote. The truck driver puts himself exactly where he wants to end up, so he knows what he's doing but it's not 100% on himDo the blades turn as the truck turns cuz it looks like they do at the end and are facing sideways? But maybe thats just the angle of the camera.

0:28 in the vid you can see the breh controlling the modules
