This photo of what looks like a minor case of Prius-on-Prius vehicular violence may actually be a piece of automotive history: the first accident caused by Google's self-driving car. Who's name should the cop write down on the ticket? UPDATE!

Sent in by a Jalopnik tipster, the photos were snapped earlier this week near Google's Mountain View, Calif., headquarters. The Prius — recognizable as a Google self-driving prototype from the roof equipment that's smaller than a typical Google Streetview image collector — appears to have rear-ended another Prius.
