Since the recent release of changing the alert to 0.2 miles, makes police alerts a worthless feature because at highway speeds, at that distance, it's already too late. In fact, anything over 25mph would be too late at that point. How about a setting that allows the user to set that distance in the range 0.2 to 1 mile to make it more practical or just revert to the 0.5-mile default that was present before the latest release!
