In car profile we currently dont support multi-value access values e.g. "forrestry;agricultural" which causes OSRM to use all those roads instead of making them inaccessible.
This is caused by a) OSRM not splitting access values, and b) whitelisting all unknown values.
I think both of these decisions need fixing. We should split the access values and process the elements individually, and unknown values should be treated as inaccessible.
Here is a patch against the car profile and the way handler to fix both issues. The restriction positive list is kept in place so delivery, destination and the like are restricted.
Positive list only contains "yes" and "permissive"
I enabled the patch in my RouteQA. Of ~200K routes in whole of Northrhine-Westfalia i am monitoring right now i had 2 roads which came out of the change in profile.
