this is very close to reality. everyone can check it in this f1 helmet cam video.
http://www.youtube.com/watch?v=1go3dL2eSYU You can see how the head view moves 15 to 20 degree on each turn. Maybe the mod is close to 20 degree and the real life about 15... just taking a look on the video, every one who want to play close to the real view of the driver, can realize the mod is very accurate. congratulations.
