Multi level towns
Living in an extremely hilly city, walking directions are next to useless. I usually get directed to my final location ,only to find I'm not where I'm supposed to be, with my actual desired location at the end of a bridge 20m above me. The routes it picks can be equally arduous, not taking into account changes in elevation, what looks like a direct route involves going up and down a valley when there's a pedestrian bridge to the side that's been ignored. Not knowing what elevation you're supposed to end up at frequently complicates things so you're never sure if you should be going up or down except when you get to the wrong destination.
