  In my eyes it makes no sense to report a bug just because of a mapdust report. Do you know taht they are correct? I just saw one in my homearea: The report was wrong, the correct information was on OSM.
  Report a bug when you know it is a bug, not when you read somewhere that there might be a bug.
  Kirchgässli Sigriswil is a very narrow road that I would not recommend to use (Have a look on StreetView) but it is possible to drive there.
