Driving Mode is a clever new version of navigation mode that uses your location history and web searches to make assumptions about where you’re going and give traffic updates and ETAs as you travel. It’s sort of like the commute feature for work and home addresses, but with some data-mining genius to make it more flexible. The new mode can be launched with a shortcut on the homescreen or from the nav drawer.
