To create its Street View service, Google sends fleets of cars to drive around cities all over the world and take pictures with the 360-degree cameras they have strapped to their roofs. The result is many things to many people: a convenient source of information, a depressing reminder that your home is ugly, an enduring memento of that time you ducked into an alley and thought nobody was looking, etc. Even though Google’s cars stay on public roads, some also consider Street View a huge invasion of privacy.
