Nobody expects self-driving cars to be bug-free-- why would we? All that matters is, statistically, that the cars are better than humans at driving. And that's something that will eventually be achieved through a combination of software engineering, hardware engineering, and spending lots of money to build trust. Some number of people will still die in accidents even if the entire fleet is self-driving. You might, if you do not already, find a like-minded crowd on the Risks mailing list, where they argue about 0.0000001% risks like "streetlights that turn green automatically when emergency response vehicles approach the intersection, fail at some rate because the designer didn't anticipate two emergency vehicles approaching the intersection at right angles" (which very very rarely causes an accident).
