Handy for real time info on where the cops are looking to write speeding ticketsYes it does. Every person using Google Maps to navigate is sending real time information to Google about where they are, how fast they are going and what direction they are traveling. When traffic stops, Google Maps knows it immediately. It even shows when a line of cars stops at a stop light.
Any turn-by-turn navigation app does the same, whether it's Google, Apple, or Mapquest because they HAVE TO KNOW WHERE YOU ARE in order to tell you when to turn.
