Its stand-alone cars Google are known to have not caused serious accidents, and as evidenced by the videos from the built-in cameras in the cars, everything else that has happened so far is blamed by another driver.
Today though was announced the first serious accident.
While self-driving cars have so far proven remarkably safe, the rest drivers they are careless. Google found this out once again when one of its autonomous vehicles was hit from behind by a speeding driver.
Unfortunately, this was Google's first accident that resulted in people being hurt, as all three occupants of the car were thrown into the hospital and were examined due to blows to the neck.
As you can see in the video below, at a junction and while the lantern was green, several vehicles including Google stopped before they passed.
