I wonder if Google's robot cars are expected to update Google Street View more or less non-stop. That would be a pretty big advantage for the company, to have up-to-the-day visual data on city streets, but it could also raise some privacy concerns. Right now, Street View is updated at intervals of a few years, in Australia at least. That's at the level where getting caught on Street View is kind of a novelty and something you might even aim for. If, however, there are Street View captures every single day in some places, then you're more likely to consider it a bit of an invasion. You don't want to get caught on Street View every single day on your way to work. You don't want the only "safe" place to be inside the car itself.

PPS - So do security cameras, but those results aren't just available to everyone.
