Yes, and every time there's a plane crash while on autopilot, Boeing/Airbus will order that every single plane of that type is grounded until the fix is found. For airlines it's not a huge deal since they have insurance for that kind of thing and they can always use other planes they have or rent them to subsitute in their schedules. Now imagine if there are hundreds of thousands of say self-driving Teslas(or any other brand) and your national safety regulator orders that they are all disabled until a fix is found after a particularly nasty crash. If you get up in the morning and can't use your car because it has been remotely disabled for whatever reason, you will be furious - or at least I know I would be. I'd sell it and buy a normal manual car the same day.

My point is, that all of this affects the public perception of self-driving cars - and if we want them to succeed, we need to make absolutely sure that that perception is good. We can't have the nonsense Tesla is trying to pull off at the moment, where they call their system "autopilot" but they know the system cannot detect obstacles at around pillar-height and it gets blinded by the sun and can swerve into the oncoming lane before just switching off. These are not theoretical problems - both happen in cars that are out there, right now. And if it happens to a regular Joe Smith, then Mr. Smith will think the technology is crap, and we can't let that happen.
