And I have some additional words:

I disagree with saying of 
"adding driveways that do not connect to a building merely because building is not mapped or ever existed is not what "silly" or
"chuckle". Driveway is a vaild objects showed on the map, unlike any mapping error or bad import (object with useless or strange  tags don't provide useful information; untagged orphaned nodes due to mapping or upload error; duplicate objects; objects that not  exist in reality...) make the objects invaild and in such manner mapper can free to remove them or asking original mapper about the mapping error issues.
