I think in the route-planning portion of the app it just underestimated the linear distance covered by a lot of tiny twisty portions. And then during the actual riding portion the turn-by-turn directions seemed to get easily confused by those very same tiny twisty turns, though I don't think that contributed extra miles, just extra exasperation on our part.
