I am absolutely biased. It's me, I'm the source :)
I'm a motorcyclist, and I don't want to die. Also just generally, motorcyclists deserve to get where they are going safely.
I agree with you. Self-driving cars will overall greatly improve highway safety.
I disagree with you when you suggest that pointing out flaws in the technology is evidence of bias, or "cherry picking to make self driving look bad." I think we can improve on the technology by pointing out its systemic defects. If it hits motorcyclists, take it off the road, fix it, and then save lives by putting it back on the road.
That's the intention of the coverage, at least: I am hoping to apply pressure to improve rather than remove. Read my Waymo coverage, I'm actually a big automation enthusiast, because fewer crashes is a good thing.
