Advice on Infringement Notice

[cowboy]

Here's what happened.

I attended the Deniliquin ute muster last weekend in the old XD. After I arrived I backed into a parking spot in the paddock and a few guys heard the idle on the old girl and called out to give it a rev. I gave it a few revs for maybe 5 to 10 seconds. Next thing a police officer appears at my window and books me for "start/drive vehicle causing unecessary noise/smoke". $243 and 3 points. I would point out here thet the vehicle was stationary, I was not spinning the wheels or anything and the XD does NOT blow smoke.

Now I would cop this on the chin if I had been is a carpark somewhere or a suburban street but this was in a paddock at a festival started to celebrate the V8 ute. I observed probably 50 or 60 other utes do the same thing and much worse over the weekend, at times within sight of police officers and not get done.

I am going to write a letter and appeal this infringement, probably have no chance but I have to try. Any advice for what I should include?
