How can I give an object realistic wind?

Hello,

I am making a driving game and would like to put some nice grass that reacts when players drive over it. It is a multiplayer game so the grass will be client-side. I have added some grass which looks nice, but I would like it to react to cars. I understand from what I have read that grass reacts to wind, so how can I make my car have realistic wind coming off it? (IE, small buffer in front and to the sides of it moving in the same direction as the car and a turbulence area behind it)

Do I just parent wind zones to it? If so, how do I set these up?

Thanks,

YM
