Now I have invented this script. It varies depending on the speed, the steering speed, the return speed (autoRotateBackSpeed) and the maximum steering angle. It also turns the camera to match the steering angle. Both functions can also be off again, with the following keys:

[LShift Left + Up]: Moving Camera on / off, default is on
[LShift Left + Down]: Look backwards on / off, default is on
[LShift Left + Space]: Shuttle control on / off, default is on
[RShift Right + Up/Down/Left/Right]: look forward, backwards, left right
[Space]: Change direction (aka shuttle control)
