I like this interpretation where one should only follow the placards, ignore the pilot and crew because they're untrustworthy, and open the door to an inferno and jump in.

The discrepancy between "can be evacuated in 90s in a simulated emergency" and "actually evacuated in 18min in real emergency with untrained members of the general public (with 100% survival despite the inferno)" just doesn't strike me as that problematic.
