I notice (perhaps wrongly? my bias showing?) that the closer successful court action looks, the more Tesla changes web terms to reflect nuance in what things like "FSD" mean.

"ready for autonomy features" (or something similar) is massively different to "will run FSD, and will drive itself" (or something similar, the view people took from what they read, when they paid extra for a feature set)

Yes. There are several articles on Electreck documenting how the wording changed across the years.

At this point both Tesla and Musk are presumed to be lying and have the burden to overcome that presumption by clear and convincing evidence.
