A button would be great to have for cars that run red lights and try to muscle in on pedestrians crossing while the walk sign is on. It would need a camera to catch the license plate, to be effective, though. Probably would be simpler as a phone app, just with a fast (or instant) camera. There's been a rash of pedestrian fatalities where I live recently and seemingly little by way of enforcement; it would be good to have some way to push back.
