I don't think a human driver could do better.
A human driver likely would not have reacted as fast, that is true. They do not give enough details in the article, but consider this:
You are driving near a school, school has just let out, you see children streaming out of the school and you see a line of cars, including tall SUVs and minivans and such.
A rational human is aware that the situation is volatile and creeps along at 10 mph. The kid jumps out suddenly and the car never hits them, not even at 6mph, because the person driving was just waiting for that to occur.
Could a human driver do better? Absolutely. Will a human driver do any better? Depends on the human.
