I didn't know this had spread outside of Pittsburgh. At a red light, the first car making a left has the right-of-way on green over opposing traffic going straight. That's just how it is.
When I was in grad school, my Human Behaviour professor, who had recently moved to town, spend half a class describing the dynamics of the "Pittsburgh Left".
