> I don't need to necessarily know the details of every twist and turn in the road so much as a schematic overview, even when getting turn-by-turn directions Some cities' street layout aren't so neat that turn-by-turn directions suffice. I often need to zoom-in to distinguish different turns by looking at such details like the curvatures of the streets and their relative placement. Even with the detailed map, I can make a mistake between similar-looking turns.
