All across the map service roads are placed into these drainage basins as they are for service access and have improvements over say a dirt track which is what track is supposed to be used for out in forests or other rural areas with no improvement.  Data like this is critical for other entities that use the map data say for emergency access or just internal use. Just cause something isn't frequently used doesn't mean it shouldn't exist on here.  Giving other groups the best available data is critical  and dirt tracks are about the lowest category of a way.  I use many sources of imagery which are newer than bings data and my apologies but none showed that change. Even many of the schools active maps depict it being one way.  If you see errors in edits the community expects you to comments and let the user have a chance to fix that error themselves unless it shows in QA as a critical error
