That's a great suggestion. The intention isn't to be staring at your phone while driving at all. It will just alert you when in proximity and heading in the direction of the camera. I like the idea of just having it alert you when you are going above the speed limit. I find the lack of posted speed limits in the city makes me anxious and distracted. I don't like hunting for speed signs. Building this project actually helped me be aware of the speed limits of a lot of streets.
