Pit Exit arrows - can they be turned off?

One of the problems of the 2D pit crew is that the shadow can't be displayed properly. It doesn't matter that much about 2D Pit Light & Lollipop Man because the shadow hides behind the car, and the player can't see the whole shadow. But about the pit crew for exit, the player can see the whole shadow, and it doesn't look natural. So, it can't be used as a substitute for the 3D stuffs. I'm sorry.
