Not to take this into 'silly analogy' territory, but I have many knives that dull after two weeks of use and others that stay sharp much longer; some that work great to fillet fish and some that I can pry a screw out of an oak log with anf be fine; but none that can do both.
And I have blankets that I sleep great under in winter and summer and others that make me wake up in a puddle of sweat. And some I take camping and others that are very comfortable but very delicate.
So no I wouldn't say that anything I own works 100% of the time. Some work more than others, and good stuff generally works in several situations (or not, when it's optimized for one use case) - but overall, if your threshold for success is 'pretty well', then any self driving tech that isn't worse than humans would be good enough.
