Right, for sure! I'm not suggesting that my analysis is correct, it's just something I've noticed in a big city with a lot of traffic lights. Red-running is endemic during rush hour, but I see much better behavior at the roundabouts. One of the bummers of traffic lights is that they tend to be more efficient with longer light cycles since you amortize the 'start up cost' of getting vehicles moving through the intersection over a longer period of vehicles moving at full speed. But the downside is that this increases the perceived unfairness because a one car length difference now means an even longer arbitrary delay. I'm not a traffic engineer either but living in a city with horrible traffic it is something I think about.
