I've really loathed my time driving in socal coming from the midwest. The idea that I cannot turn left on green is one of the more appalling "features" of traffic management here (the way the lights work, in general is abhorrent). But slowly, throughout socal, I've seen the flashing yellow left-turn arrow; a subtle change to the UX that I think is brilliant and should be adopted everywhere.
