When calculating the route from Effnerplatz to Occamstrasse 10, the router (Car - OSRM) refuses to use the Isarring, the motorway inside the city.
The resulting path is incredibly longer and illogical.

A guy noted that the little road for accessing to the Isarring is marked as "psv" (public service vehicles). That is an error, I access to the Isarring almost every day.

Note:
GraphHopper and Mapzen returns the correct path indeed.
