The problem is the "hoon" laws are ambiguos. So if a police officer hasa nasty streak and takes a disliking to you they can find something to categorise you as a hoon. If you accelerate off the lights, even if there is no wheel spin, smoke or noise they could still claim you were hooning even though there was no specific rule broken. If they want to target bad behaviour, no problem, make sure there is rules and supporting legislation that targets that specific behaviour.
Its much like the bikie laws. They target a broader group because of a minority that do the wrong thing. They need to stop being lazy and target the specific behaviours.
