Google Maps Navigation is already a killer exclusive Android app that Google offers at no charge. That doesn’t stop them from improving on an already amazing service however.
Navigation has always tried to find the best possible route using the time of the day to estimate avoiding traffic. Now it does this in real-time and attempts to get you to your desire location even faster than before.
This new feature is available in North America and Europe where both Navigation and real-time traffic data are available (that includes Canada!) I’ve yet to try this out personally but give it a try and let us know how you like it.
