OLD DESCRIPTION, BEFORE I KNEW THIS WAS A SELF-DRIVING CAR: They must be testing the latest Mapping car a lot lately. Seems I see them on almost every trip. I'm not sure what company they work for, I've always assumed Google but I see these cars quite frequently in Silicon Valley. This time I had my HD camera ready. Note that there's two cameras on top: one that looks like it's recording video (the black thing on top) and one that's recording stills (the rotating camera). Also note that they didn't like me shooting video, when they noticed me they slowed down quickly.
