I think the point, though, is there should be a redundant system to handle failures, like a mechanical-only door handle.
Another example: your dashboard touchscreen fails, there should still be a button to turn on the AC. Or off. Whatever makes this analogous to the safety concern about doors.
None of those things replace that content, though.
