The Norvus Mini-Coyote is a dashboard device that alerts you to upcoming police speed traps. Available in the UK, the device works by user participation instead of actually detecting radar. When you see a speed trap, you press a button on the Mini-Coyote which sends a signal back to the main database. Then anyone who drives by that particular spot within the next three hours will receive an alert before they reach the trouble spot, allowing them to slow down in time. The system allows for real-time alerts which is helpful to avoid mobile and temporary speed traps. Users can press to alert for other traffic issues such as construction and red light cameras. When approaching speed cameras or danger zones, Mini Coyote shows the speed limit at this location, it alerts the driver in case his current speed exceeds the speed limit

That’s actually quite useful. I wonder if the 3 hour time limit is extended if lots of people submit the location as being a speed trap?
