HI Maruti, When I've used mouse for steering I've always implemented a scheme where the delta of the mouse form the center of the screen sets the speed of rotation, for an example of this see the DriveManipulator. This way you never get limited by mouse movement beyond limiting the maximum speed of rotation.
