When Emma comes home and Bruce is preparing lunch she gives him a kiss and leaves red lipstick above his upper lip. First the lipstick is smudgy, later it looks almost like it is drawn in a clean line.
The taxi Bruce "drives" seems to be on a trailer, since the car behind them is lower than the taxi. Bruce mentions the "farthinder" which is a speed bump, but they never drive over it. When Bruce stops the car midway while turning right and Hassan takes over the wheel Hassan keeps driving straight ahead and hasn't finished the turn.
It is rare that taxis in Europe have a manual gear box. They mostly have automatic gear boxes. The way Bruce is moving the shift stick would not be possible without using the clutch. Which he referring to Hassan not does. If he moves the stick like that without using the clutch he would damage the gear box.
