Every sentence you wrote contains the word 'will', so they are 'forward looking statements' and evidence free. I understand that we'd like this to be so but there is no guarantee that it will be the case and a single, non-redundant sensor going down could have immediate impact on the cars ability to get itself off the road in a safe way.

This wasn't about opinions but about the state-of-the-art and the facts as we know them today. What will happen in the future is anybody's guess, my guess is that before long there will be a couple of major crashes involving self driving cars resulting in mandatory redundant systems and redundant (quorum based, see Animats' comment) processing units. Otherwise self driving cars will end up with a bad reputation, even if the chances of failure with any individual vehicle are small.

Statistically speaking the number of components and the their internal complexity are good indicators of how frequently you can expect such a system to fail. Self driving cars are sufficiently complex that these are legitimate sources of worry and simply waving those worries away with what 'will' happen does nothing for me, it is the how that interests me.

Ofc they will fail at some point, there is nothing magical about a self-driving car. What I meant with the previous post is that it could be fail-operational see for example the volvo drive-me.
