A while back they changed things so that machine guns vibrate some and the planes shudder a bit as they roll down the runway. Could this type of artificial shaking be added to GVs? Having it so that the shaking gets worse as speed increases. It would not slow anyone down, but no one would be firing/able to look out the gun sight effectively while moving at full speed. Right now it is just some mild rocking. Adding some rolling or other random motion would increase this effect.
