Here is the simple route showing the issue:
B8 at Feusisberg (CH)
The detour through the industrial area is only at “curvy route” and not “fast and curvy route” selection. Even more: on the crossing back to the B8 a left turn is forbidden (Google Street View).
I have tried to use this “feature” to block this routing by adding restriction=no_left_turn, however this doesn’t seem to work (I am far away from having skills in OSM mapping, so probably I used the tag in a wrong way).
Is an OSM expert around who could check and help me fixing this routing issue?
Thanks a lot,
