Even when my light was green, I have seen cars still go through the intersection.
I even had "Angry Old Man" behind me once, coming off the motorway to turn into Birmenstorf last year; he was angry that I didn't run the lights, despite the large quantity of photons clearly being emitted from the orange light, long before I was at the stop line. He continued to tailgate me all the way to Birmenstorf and appeared to be shouting obscenities at me from inside his car, which obviously I could not hear. What a tosser!
