99% of normal folks are not technical like most of the people on this board. They will use the WiFi straight out of the box without setting up silly things like passwords and encryption.
If I could tell from your user data that you were visiting a bunch of luxury car sites, and the street view showed that it was coming from a large estate. I would have a salesman knocking at the door right away.
In other words if I can tie your demographics(by scanning streetview images) to your surfing habits that makes for an extremely accurate marketing arena worth gadzillions to companies.
