CNET's Chris Matyszczyk asked a few of those tough questions in a earlier today:

"And, though Google might--in a left-brained manner--want us to believe that is human error, its deftly phrased spokes-quote didn't suggest there was any error at all," he wrote. "So the 'person' was 'manually driving the car.' But no word on whether the 'person' made a mistake. Or whether the car did."

Matyszczyk asked Google to release more information on the incident to try to get to the bottom of the situation. Google only offered one additional bit of information: the car's logs confirmed it was in manual mode.
