@ctl - You've never made an argument why you think adding driveways to unmapped houses is useful. You just keep repeating that because driveways exist that they should be added to the map (this isn't an argument OSM accepts; there are plenty of things that should not be mapped).

Why do you add them? What benefit do you think they provide?

Also, the driveways often intersect with Microsoft's open buildings datasets; this causes validation errors when I add the houses.
