To me, that's evidence that it's performative. First, it's a talking point; it looks, smells, walks and talks just like typical corporate/industry framing and messaging, with even a 'think of the children!' line, and the redirection (from the safety of autonomous cars, the topic, to whatabout something else). Second, its repetition by Urmson is further evidence - that's how talking points work. Third, the public's reptition of it, in surprising detail, such as in your comment, is also what we'd expect. Finally, throw in some tears, 'I get emotional' lines, etc. (per the NYT article), and I don't know how it can be missed.
Could it all be legit? Anything is possible - including fully autonomous cars!
