Are you saying that these are cops in unmarked cars? I was talking about the cameras which are outsourced by the government to private operators. These cameras are ALWAYS in cars which are stationary.
As for commodores and falcons coming up behind you- yeah you have to be careful that they're not unmarked cop cars.
