Rather than being a bad thing, this is probably Waymo saving his life.
It says the car reduced speed from 17mph to 6mph before contact. This is the kind of reaction-speed safety an AI car should have over a human driver - instead it’s just ‘waymo hit a kid’.
After passing the Genesee exit, Aguilera Mederos's truck began to smoke as he passed a runaway truck ramp, without taking it, and instead drifted into the left lane nearly clipping a white Chevy Silverado, and passed the next exit as well. For the next few minutes, Aguilera Mederos reached speeds upwards of 100 miles per hour (161 km/h)[6] and passed the next four exits.

I'm not saying a human driver would have done better. I'm disputing the claim that a human driver would have necessarily done worse. There is not enough information given to reach either conclusion.
