No! Click on this link & look at the CGI of 4D track
http://www.coasterbuzz.com/features/trackspotting101/ See the extra rails? One on either side of a new style Arrow track which is reinforced. Small wheel assemblies ride the rails & control the spinning of the cars via a connecting rod. Depending on whether the pitch rails are lined up with the main rails or at the bottom inline with the ties, one way or other, one position keeps the seats upright & vice versa for the other. However this restricts the rotation to 180 degs either direction. Otherwise it could be a 'endless loop' cranking of the seats much like a engine piston's movement.
This means one side of seats could flip one way & the other side the other way! Or one side could be inverted & the other upright. Just have one pitch rail at the top & the other at the bottom.
Therefore the operators don't control the rotations. Head banging? I would be more concerned about head flipping or whiplash from the rotating, wouldn't want to hurt my neck. People have said Arrow's latest coaster, the Tennessee Tornado is very smooth & features their new track design, there is a good chance X will be smooth.
I just hope the rotating is tame as if it's extreme, you'll hear the sounds of puking, maybe from me as well! :)
Otherwise, X looks awesome!
