Google just put another nail in the coffin of dedicated GPS units and paid mobile apps. Google Maps Navigation now offers users the ability to route them around traffic jams. Until today, Navigation would simply calculate the most efficient route and send you on your merry way without checking traffic conditions. The new version, however, will look at both current and historical traffic data to calculate the best route to take. According to Google, Navigation users now use the app to drive more than 35 million miles per day.
