Revealing mistake: In the scene with the helicopter chasing them down the street, apart from the fact that the rotors should catch on something and hurl the machine into a wall, when it finally hits the wall at the end, the pilot and crew quite clearly become about 4 crash-test dummies. This wouldn't be so bad if it weren't for the fact that they are unpainted and all sit in their seats looking straight ahead with their hands in their laps while they are driven into a wall. You'd think they could have at least posed the arms over their faces or SOMETHING!
Answer: It's getting dark by this point - Bond and Wai Lin are dressed in black in a dark coloured boat. Anyone looking out of the window would be looking down towards them - they wouldn't be able to pick them out against the sea.
