Every time you drive on the highway, there are always spots where cops will hide out. Most people will slow down near no u-turn areas because they know of cops hiding there. When somebody makes a report of a cop in an area multiple times, zones or blue circles should be lightly covered on the map and fade over time. These zones will let users know "hey cops like this area a lot" or "ok cops do camp out over here just not recently". I think zoning is an easy thing to add and it helps people slow down in common cop areas!
