Gotta love wankers like you mate. I've not had a fine in over 12 years except for one, even with several car pulling in excess of 200rwkw, plus a 500hp GTR. I'm also a defensive and offensive driving instructor, and race a dedicated race car.
I'm also only an Engineer with specialisations in guided weapons (using real laser and radar systems) and believe me when I say that these cameras and hand held devices are pretty damn innaccurate, so it isn't a case of not speeding but protecting yourself from their inherent faults.
Don't bother responding, I'm not in the mood for a battle of wits with someone who is completely unarmed.
Otherwise, if you are caught folks try here....

I have no other affiliation other than I use their techniques to fight a speeding fine of 64 in a 60 zone. Added to my expertise I have no doubt I will not fail if it goes to court.
FoX is on the money. They are revenue raising and nothing more. Any intelligent human can work that out. 500 million in Vic alone last year. Think of the money not going into the local economy. Greedy Labour govts. Talk to you local member and tell them you will support them if they oppose speed cameras and support real education.
