The highway=service tag denotes ways used for vehicle access to a building, parking lot, service station, business estate, beach, campsite, etc.

And also:
https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrack
The tag highway=track is used for minor land-access roads that are not considered part of the general-purpose road network [1]. Track roads are mostly used for agriculture, forestry, outdoor recreation, and similar activities on open land. **Roads used for access to permanent human settlements or facilities should generally not use this tag.**

😀
Mind that Car Navigation Apps ignore tracks, by default.
