We understand your frustration.  OSM runs into this issue routinely.  

Service road is just a classification OSM uses.  Driveways are considered a subset service roads.

This driveway has been tagged "private" to both vehicles and pedestrians, which means any routing engine will not use it.  

Everything was tagged correctly, and removing correctly tagged features is considered vandalism which is why the change has been reverted.

Anybody making the mistake likely is not using OSM or should be reported to program using OSM data cause their program has serious bugs.

I have mapped the woods around the property to help people realize they can't drive/walk through the area.
