Thanks for this note. Current status:
1. the highway classification was incorrect. the purpose of this highway is more a service road, but not to reach out to farmland / forest areas (now set to highway=service).
2. no change to the access limitation so far: the highway is already tagged with "vehicle=destination" (https://osmtools.de/traffic_signs/?signs=250,1020-30), will double-check if this correct or it has to be modified into "vehicle=delivery"
3. no change to the surface. Will survey this detail on occasion.
