In regards to privacy, Google is proactive. The algorithm blurs faces and license plates automatically, as noted above. However, for some, that is not good enough. If requested, Google will blur your house or other building, such as an office. This is just what happened in Munich, Germany. It just so happens that the building that had been requested to be blurred also housed corporate offices for Google itself. They had to blur themselves out of Street View.
Most of Germany is not included in Street View due to privacy laws and a general attitude towards privacy in Germany that goes back decades. Big Think explains that the collective experience of having been terrorized by the Gestapo first and later by the Stasi has affected the populace today. Google mapped out 20 cities and ran into so much trouble it has left Germany largely without Street View to this day. This building is no longer blurred, but there was a time in Munich that it was unavailable on Street View.
