Turning the turret in the third person causes a noticeable shake
Pressing the right mouse button to switch back to third-person view from aiming will force the camera to focus on the front of the car.
Pressing the right button to toggle the aiming state in third-person view will result in a very noticeable black parallax, the severity of which depends on your viewpoint and the orientation of the turret's pointing point, and becomes more noticeable the farther away from the turret's pointing point you are from the viewpoint.
The first video is the current version, the second is the old version
