Corrected entry: During the chase scene, the Mustang's rearview mirror usually shows part of the driver's face, either Bullitt's or his stunt double's. While near the end of the chase on the hill, when we can see the water of the Bay, the Charger can be seen (from within the following Mustang) having a hard time turning left. The Mustang's rearview mirror shows the stunt driver excitedly chewing gum, but Bullitt is not chewing gum.
Corrected entry: Steve McQueen changes up a gear about 19 times.
Correction: At best, the Mustang goes through five distinct gears when accelerating after the slide to avoid the cyclist, then catching up to the Charger. At that point, the camera angle changes to inside the Charger, and the driving becomes erratic. A slow-down was certainly possible, putting the Mustang down a gear or two before we hear further upshifts. As for five gears, the car is wearing aftermarket wheels, right? Who says it can't have an aftermarket-prepped 5-gear trans, for the movie's sake? In reality it didn't, but the character could have made the change.
Corrected entry: Jaqueline Bisset and Steve McQueen are driving in her yellow Porsche on the busy freeway. A grey saloon and 3 red lorries feature behind in the shot. Bisset and McQueen stop the car and get out for a chat on the side of the road. They then get back in and drive off, with same grey car and 3 red lorries behind them!
Correction: At the start of the scene a blue car is on the off ramp as McQueen and bisset pull off the highway in the yellow Porsche. After the cliff top scene it cuts back to the highway and the same blue car is just leaving the highway with the yellow Porsche 3 cars behind it. They just used an earlier piece of the same shot.
Correction: They are not shown driving away in this scene. There is a brief shot of the car parked on the shoulder, and one red truck can be seen approaching, but it is a highway and there's probably other red trucks traveling there.
Correction: Just because we don't see the gum placed into his mouth, and just because in some shots he isn't chewing, that doesn't mean it isn't there. The face in the mirror is indeed McQueen himself, and he is obviously actually driving the car in the chase, hence, Bullitt is chewing gum in the chase.
