Yes, for the routing between e.g. 48.19383,16.41089 and 48.19453,16.41164 I would go through the tunnel (https://www.openstreetmap.org/way/196792183) left of Ströck (https://www.openstreetmap.org/node/2334713974), go left of the building (https://www.openstreetmap.org/relation/2721701) and over the bridge (https://www.openstreetmap.org/way/1150760225), so an almost straight direct line, but e.g. GraphHopper routes along the edge of the whole area (https://graphhopper.com/maps/?point=48.19383%2C16.41089&point=48.19453%2C16.41164&profile=foot).
