Have you ever been a good distance from a green light and wanted to accelerate just in case it turned yellow? Barely squeaked by in a yellow? Blatantly ran a red trying to make the yellow? Screamed in rage at a red light when you're running late for work/a date/your reckless driving hearing? Well, there's an app for that.
SignalGuru is a smartphone app that predicts when lights will turn and tell you the speed you need to just cruise right through every light you see. We want this right now.
