Interestingly, if one moves the stop position from https://www.openstreetmap.org/directions?engine=graphhopper_car&route=46.5258%2C6.5621137%3B46.5227814%2C6.5174317 to the front of the building towards the Avenue de Morges, then the route quickly snaps to the seemingly correct way.

Maybe a workaround in this case would be to move the 'Studios PHD' POI to the front of the building, so that the routing generally snaps to there...
