Here's a short 3-lap example from a single race at Donington Park, taken from the surprisingly realistic experiences of Need for Speed SHIFT.
Not only does it add so much more realism to the in-car experience; it also comes in very handy in giving a quick glance to the left or right during overtaking, whereby, for some reason, it doesn't seem to put you off so much as it does when using the look around on the right thumb stick.
It's great fun to be able to 'lean' right over to the passenger side or put your head into a corner etc.
For those of you with NFS Shift on PC, this handy little plugin that was used to make this video; is called
Need for Speed Shift Camera Control v1.1 & was made by Racer_S. It enables customization of camera properties within game & also provides full Track IR support. It can be downloaded here:
