Is what you consider a driveway actually a driveway legally speaking? In rural areas even if you own all the property around the roadway, the road itself might be a public easement.
The driveway was put in by my father - so no it is not a roadway.
I think there was wishful thinking since many of the OSM maintainers are mountain bikers and the Santa Cruz mountains has some desirable mountain biking paths. The back part of our property is on The Soquel Demonstration Forest which has an awesome mountain biking path.
They were pretty good about fixing the issue when I pointed it out.
That case sounds like a bug/algorithm issue with address lookup software. If the OSM data is correct, then it would make the same mistake with any other correct map data source, right?
But in this case, it sounds like the issue is that a private driveway is mis-labelled as a public route. This sort of thing is trivial to fix in OSM.
