You make it sound like it's a 50/50 split between human drivers and autonomous vehicles, which is definitely not the case.
There are way more human drivers than autonomous vehicles. So, when an autonomous vehicle runs your child or pet over or whatever, who do you blame? The company? The programmers? The DMV for even allowing them on the road in the first place?
What's an autonomous vehicle do if it gets a flat? Park in the middle of the interstate like an idiot instead of pulling over and phone home for a mechanic?
