There are occasions when a bad layout of lights can cause this through a driver spotting the wrong light as they change, I've done this.
First look my light was on green, when I looked back after checking the traffic it had changed to red but I saw a light on a different lane on green that was pointing towards me and interpreted that as a green light for me.
Personally I think in that case it is a bad layout of lights. I will admit to being a bit tired, but not so much so that I was unfit to drive.
Now if people want to rip me apart for this error then do so, there was no accident as a result and no one was forced to avoid me, this helped with the error as the junction was completely clear.
Crooket Billet roundabout (the flat flyover) at Staines is a good example where lights are badly set out so people mistake the next lot of traffic lights as their lot, so go when they shouldn't.
There's also a roundabout in MK (yes there's LOADS of them I know) by the hockey stadium and McDonalds, traffic lights all around, set so that when one lot goes green, the next is still red, so you hit every red light.
However, if you go round just as the lights go red, by the time you get to the next set, they're just turning green, and I've seen people do this to get round without having to stop!
Do certain streets in London still have the green wave? Where as long as you stick to 30mph you'll only ever supposed to hit one red light as the timing is just right?
As for 23 past a school at 3am, you could have speed limit windows, so during 6am to 9pm 20mph, all other times and weekends 30mph.
It's also been shown that the light up speed limit signs which come on when someone's going too fast have a longer lasting effect on people staying within the limit than cameras.
As people have said, drivers slow down at a camera then speed up again, I'd guess because they feel they're getting one over the authorities, whereas with the light up signs, more slow down and stay slowed down.
The difference between being ordered to do something, and being asked politely I guess.
Course, light up signs don't bring in any cash, which is why there are fewer of them than gatsos.
