Same thing down under - if you don't pay, they don't renew.

Red light Camera's and speed camera's here have sign's warning you they are there - and you can requst a copy of the photo if you don't believe them. And the photo shows the light as well as the car, so if it goes off on Amber instead of red you have proof you are OK.

Not all of the camera stalks have a camera in them - but you don't know which ones are live this week, so you treat them all as potential traps. Increasing the number of points where they can be placed ain't revenue raising because the number of camera's has not changed - but it does impact driver behaviour.

It's easier to just watch your speed and slow down and stop when the lights go amber. I hate last minute jumping on the brakes when you realise you're not going to make it - and you hope the guy behind you has brakes which are better than yours.
