The mirror is one thing, but anything/anyone that considers passing distance=0 acceptable is, by definition, unfit for driving. The Tesla drove as if the black car did not exist at all, never correcting its distance from the curb (which it did for the previous car).
It would definitely be interesting to know if the Tesla 'saw' the black car at any point (and what it was identified as), or if it just looked like another piece of tarmac and kerb. I'm still pretty skeptical we'll ever see safe full autonomous driving other than on motorways, and even then probably with some additional road infrastructure.
