Seriously!! This is nothing more than a way for these cops to try and keep their money flowing in from those that don't obey the speed signs. How is this any different than being on the phone with a friend as you drive and mention you just passed a speed zone? Give me a break... WAZE is by far, one of the best apps available, especially for serious drivers. It not only gives you notices of objects on the road, traffic, as well as weather issues causing possible driving conditions to change.
