I didn't say you did. I suppose you could interpret "I don't think it's safe to say X" as referring to your speech, but I read it as "I don't think X".

Well, I never asked you to debate it. It's a relevant because the TechCrunch article that we're discussing does imply that Autosteer or Autopilot is principally responsible for the 40% reduction in crashes, and in my first comment I expressed my doubts on the claim.

I would agree that "a combination of AEB and autosteer" is possibly the real reason behind the reduction in crash rate, but I would point out that while we already have strong evidence that AEB alone can lead to a large reduction in crash rate we cannot prove or disprove that Autosteer's impact is comparable.
