It's 1-2 o'clock in the morning and you're nearing the end of a long road trip. The Cumberland Farms coffee buzz is wearing off and your Chex Mix is damn near gone. You pull up to an intersection right as the light is fading from yellow to red. Great. What happens before the other light even gets a chance to turn green? An all-way-walk signal. Awesome. You look left and right, front and back, even up and down, but there isn't a pedestrian in sight. So who the hell pressed the button?
