Lots of options where Kev (thisnameistaken) told you to look.
I turn off all head movement in sims, because it's wrong foremost, and it gives me a headache. In a real car your view doesn't move around, even when your head moves, because your brain cancels out the movement from the view. If driving an F1 car in real life was anything like the normal view people use in sims then nobody would be able to do it, and their eyeballs would explode.
I suppose it does artificially increase the sense of speed for people that think going fast looks fast (it doesn't by the way - the faster you go the slower everything goes by, as it's usually further away and you're looking further up the road anyway).
