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.

If the software they are connected to doesn't know what to do when the camera fails or starts sending bogus data or even to detect that it happens you still may have a lidar, radar, etc. but it doesn't make the system fail-safe.
