Thanks for the reply! Yah OSM it pretty typical to see driveways mapped. Think of OSM as an "open geospatial database" rather than a GIS Map.

It seems like these features were not added by an automated system, but if they were, that would not make them invalid.

If you need a map free of driveways and other features, you can freely export data to QGIS or other GIS software and create/distribute any sort of map you like! (Maybe check out maptiler or maputnik)
