NOTE: I made a note for Nordre Fasanvej 34.  See https://www.openstreetmap.org/note/5127697

I forgot to write in that note that the routing error happens when you enter a routing from Nordre Fasanvej 34, Frederiksberg towards Sønderjyllands Alle 25, Frederiksberg. 

If the destination is changed to for instance Finsensvej 12, it does not suggest a route towards north with an unsafe crossing and double back towards Stæhr Johansens Vej. It suggests a crossing at the intersection at Stæhr Johansensvej as I suggested in my note 5127697.

The route towards Sønderjyllands Alle 25 is important for many as it is a route towards a local highschool.
