I’ve yet to find a modern use for usenet as I’m not in the habit of downloading everything as it comes out, nor of looking for content within a few days of release. Often I’m looking for 2-5 year old content or back catalog, and usenet has been a uniform landscape of incompletes, even with two blocks on independent providers (or they were when I bought the data blocks).
The description of an unexpected/(impossible) orientation for an on road obstacle works as an excuse, right up to the point where you realize that the software should, explicitly, not run into anything at all. That’s got to be, like, the first law of (robotic) vehicle piloting.
It was just lucky that it happened twice as, otherwise, Alphabet likely would have shrugged it off as some unimportant, random event.
