I just gotta say, some people are far too harsh with their comments. Stop pretending you're perfect drivers and never make a single mistake!
I was thinking about this the other day. 2 weeks ago the light changed to amber really late, I panicked a bit and didn't know whether to brake or accelerate. I accelerated. It was wet at the time and I did't think that braking would stop me in time.
I learnt from that and reduce my speed in anticipation when I come up to lights with cameras. I'm not so sure theres someone watching the road, ready to turn the light red on unsuspecting motorists ;)
If there should be a delay of 1 second and you got flashed at 0.9 i guess you might have a bit of hope pursuing that. Less than a second is hardly reckless.
