> In aeroplanes as mentioned above they have no choice, but other vehicle safety systems may be considered just as vital even though they always have the last ditch "I give up, stop everything and let the humans fix it" option which in an aeroplane violate that "nobody dies" condition because we can't turn off gravity while we fix the problem.

They still use that in aircraft - George will give up and hand back control to the pilots. The Air France crash over the South Atlantic was caused by that exact scenario.

And the problem is that even that scenario is real-time - it can often take longer for humans to take back control, than time is available ...
