It only gets worse.
You Sods... Stop your whinging.
Here in Melbourne Oz, our redlight cams are so old they're rusting and being replaced with the next generation of revenue raisers. The 'Speed & Red Light' Cam combo.
Nice isn't isn't it?
We can get done for speeding (we have a 3Km buffer too!! They so naice.:rant

and red light breaches in one hit. I guess they've done it just to save us time. Thoughtful.
On the topic of your redlight cams, here are some things to think about. Firstly ours only take from the front. And secondly, they typically are not all active at once. They install the pole roadside but move the internals from point to point. At least thats what they were doing here until these new items appearred. Keep in mind that there are many models available globally so yours may work in both directions.
And I'm qualified....
Melbourne is apparently the most heavily road-camera-policed city in the world, netting AUS$450-500M per annum in a city of only 4 million.
We have a wide range including fixed cams, mobile cams (not cops), redlight cams, bus lane cams, The fixed items on most freeways that earn on average $260 per minute. (sorry TOO FAST but a waste of money they are not.) Make no mistake folks every government on the planet will develop a similar addiction to this revenue stream before long.
The reason??
They can get away with it all in the name of road safety!! AND continue to blame us when the road tolls aren't in alignment with their "Preventative measures".
On the upside, we (bikers) don't have to pay tolls. They tried it and the Motorcycle Riders Association staged a protest. A few thousand of us all did laps of the most congested part of the tollway during peak hour. Seems to have worked. They canned the idea.
Yay.
However, our gov is investing $16M to develop some method to identify registraion in the front of all bikes.... Because they don't get revenue from us.
