So Delta had a TCAS RA and responded to it. That’s not really news or anything particularly unusual. I think I get around ~2-3 RAs a year or so, usually because someone is climbing or descending fast and TCAS gets scared because it doesn’t know when the planes are going to level off.

According to Ol’ Elon the robo-taxi service has been a couple months away since 2017 or so. I can’t imagine it’s much closer now than then.
