I checked all the access tags between PCH and here.  They all appear correct with vehicle access set to private.  If there was an issue, it would more likely lie with the app that uses this data.  OpenStreetMap is separate and independent from Google, Bing and Apple Maps.  Between you and me, most people do not use data that relies on OpenStreetMap.  I would encourage you to report problems with their maps to ensure that they will update their maps to be right.
