Shang-Chi's bus scene reviewed by an SF bus operator! (Unrolled.)
Our bus operator discovers his service brake isn't working. He's mashing on the treadle (pedal) and not stopping. That's terrible! And he's wearing earphones. That's terrible. He definitely could be charged with an avoidable incident by SFT. He should be reaching for the Parking and Emergency Brake on his left control panel.
Update: And here's a pretty great video with the director breaking down the whole scene.
