Google's self-driving cars have apparently had their first fender-bender — and it was a person's fault, the company says.

The car blog Jalopnik posted the above photo of one of Google's self-driving cars, which they identified by the rack on the roof that resembles a smaller version of the Street View setup. It appears to have rear-ended another Prius, to the obvious dismay of the people gathered around it.

But shortly thereafter, Google gave this statement to Business Insider: "Safety is our top priority. One of our goals is to prevent fender-benders like this one, which occurred while a person was manually driving the car."

So it wasn't the car's fault, apparently. Good news for those following the forthcoming wave of autonomous car technology.
