If I'm not mistaken, doesn't a screw drive like this use the "slipping" of the screw thread along its length to achieve the forward momentum of the vehicle? Sure sideways would benefit with having tread along the edge of the thread (say that 5 times fast), but forward/backward would then suffer.
Am I right here? I've been Youtube walking through the videos showing this type of drive and pretty confident in my impression.
