It's a parking sensor. How many parking garages are textureless walls? Borrowing phrasing from the grandparent: "promise the impossible" may indeed be bad marketing, but "demand the needless and infeasible" is at least as much a problem here. Everything, everything about Tesla has to be some kind of existential argument about how This One Thing Proves Everything I Hate. And.. it's still just a parking sensor.

Meh. I have the sonar equipment in my car and it works nicely, and I'd view its removal as a mild loss. But it wouldn't have changed the purchase decision. It's a technical mistake, and at the margins will probably hurt them in sales.

But there's nothing here to justify the size of the thread we're spending on it. It's a parking sensor.
