180 truck like movement when standing still

[playertwo]

so standing still and lets say a zombie is behind you and you try to hit the zombie. you fling around like a mac truck would instead of just turning on your heel. 

 

I understand if you have some/any speed you should have to arc around even a small amount to turn right around but this is to the point of being annoying.

 

There shouldnt be a huge arc/turn when your not moving like that it theres already enough to punish the player for not seeing a zombie quick enough.
