My impression -- and I could be wrong, I haven't seen a lot of discussion of the Spider since the early stages of the case -- is that it was less similar than it initially appeared.

Do you know of any place with actual transcripts of the entire hearing?

My reading of the article was that they'd dropped patents from the case entirely, but that quote might have been misleading.

I don't. I do remember Judge Alsup raised concerns about Waymo being able to show damages from these patent infringements a while ago. I believe that this was part of the reason that Waymo revised their claims, and might point to why the spider prototype isn't as much of a smoking gun as we expect.
