It's so awkward to arrive at a red traffic light, see that there are no cars and I don't go anyway for some reason. When I've stood there for a bit, despite the complete lack of cars, it's quite hard to decide if I should become a jaywalker or just stick to my commitment of being a responsible pedestrian.
Then some savage shows up and disrespects the red light and I go "ok, I guess I could do that too." So I scurry after them.
