> “Our driverless operations have always performed higher than a human benchmark, and we constantly evaluate and mitigate new risks to continuously improve,” said Erik Moser, Cruise’s director of communications. “We have the lowest risk tolerance for contact with children and treat them with the highest safety priority. No vehicle — human operated or autonomous — will have zero risk of collision.”

Notice that this contains nothing of substance: no "human benchmark" is actually defined; nobody was asking if they constantly evaluate risks (do they also remember to breathe in and out every few seconds?); "the lowest risk tolerance" is meaningless, as is "the highest safety priority"; and obviously no vehicle will have "zero risk of collision", just as no vehicle has zero risk of being hit by a meteorite.
