I have only see this twice first hand (from motorists, that is - my lycra buddies (they're not REALLY my buddies) do it most of the time!!).
The frirst time:
I was approaching a series of traffic lights, two lane approach. I was in L1, and ahead was a Mondeo in L2. The lights phased from Green to Amber as he was approaching and went from Amber to Read about 1.5 seconds before the Mondeo crossed the line. Illegal, but not the most unsafe piece of driving I have been witness to on the roads. He was carrying a fair turn of speed (I'd guess about 25-30 MPH) and was through the lights and clear of the junction before the cars in the adacent junction who were probably Red+Amber (i.e. prepare to go) were just starting to move.
The second time:
Chav boy racer was bored (I assume) and just drove off through the red light (he was obviously first in the line) when he saw that there was no more traffic coming from the other junction. In other words, he treated it like a give way I suppose.
Not sure why, but the second incident really annoyed me. I was forever muttering about young drivers and taking chances etc etc.
I may (yes, may, officer!) have gone through a red light that had only JUST changed to red when I was literately feet away from the line. My excuse was my mind was elsewhere (driving to hospital, missus going into labour).
Bloody disgusting business, childbirth is. Wish I was late now

/edited to add: Just to clarify the above: the missus wasn't actually IN the car with me when this happened, she was already at the hospital with the IOB (interfering old bag, a.k.a. MIL) and I was, obviously, driving to the hospital to witness the miracle of afterbirth etc. I got to play the gentleman when MIL feinted. Joy.
