i wouldn't have sped up when they went to pass me ("Never get between an idiot and their destiny."), but the part at the street light where they just sat there on green for multiple minutes.... i may have considered getting out of my car to invite them to move along (I'm built like a fridge, while my vehicle, general style and countenance say "I have nothing left to lose") or calling traffic safety to report the plate as a "possible drunk driver", because that was pretty egregious. cars are the problem, but that person should not be behind the wheel.
