yeah... your head can move a LOT more than you think is possible. Check out how far my friend's head moves in this video at about the 12 second mark. And this is with a proper seat, belts, and HANs.

If you install a right side net proprerly, it literally wraps tightly around the right side of the seat befor it takes a direct line to the dash. I got one just from watching this short clip.
