Google Now is genius… most of the time. When you first enable it, it takes a couple of days to get started then it figures out where you live, work, go to the gym, and your other favorite places. Then it starts letting you know how long it’ll take you to get to those places depending on the time of day and your previous history of travels to that location.
The problem with Google Now’s predictions though is that sometimes they can be inaccurate from the start or take a little longer to adapt to change.
