Are these things caused by loops or turns? I've always wodered that. The same with headbangin'. Is it caused by turns or loops. I've always thought it was corkscrews what some turns like on FOF made my head bang against the shoulder restraints. What do you people think?

Laterals are forces that push you against the side of the car.  The primary source is turns.

Head banging occurs when the train makes small quick movements to one side.  This can be at the start or end of a turn, but can also happen or a straight if the trains motion isn't stable and it jerks back and forth.  Basically, inertia causes your head to try to keep going in a straight line while the train moves to one side or begins a turn.  You might say that what actually happens is the train hits your head rather than your head hitting the train.

This is why so many people hate OTSRs.  The OTSR puts something close to your head that it can bang into.  Remove the OTSRs and your head may flop around a little, but there is nothing for it to bang into.  I noticed this very clearly when I first rode Flight Of Fear after the conversion to lap bars.  There were still sharp lateral jerks to the motion, but there was nothing for my head to hit, so no pain.

Lateral G are usually caused by sudden change in sideways movement. Which means that most of the time turns are the cause of laterals. Yeah the corkscrew on FOF does cause a lot of lateral's which result in head banging and also most of the banked turns cause major handbanging. Most of the tine head banging is asscioate with laterals and the best examples are B&M coasters which have very little head banging and not a lot of laterals.

Also, the B&M OTSR's are so big and roomy, that you can move your head around a lot and not hit anything.  Also, the B&M OTSR's hold you in by your pelvic area.  Not your shoulders, like on Arrow, Premier, Vekoma, etc...If you're smart, and you think about it, it'll make sense why the B&M's have less headbanging by the way you are held in.
