Other mistake: At the very end of the final chase, Vincent fires his gun and the BMW wheel was slashed. But Vincent aims his gun to a higher position, not to the position of a car wheel.

Sam: Either you're part of the problem or you're part of the solution or you're just part of the landscape.
Trivia: In many of the stunt car scenes you can see the actors apparently driving. The producers used British RHD cars and fitted phoney steering wheels on the passenger sides to make it look as if the stars were really driving.
More questions & answers from Ronin
Chosen answer: It is true that it doesn't affect the plot. However Spence's (Bean's) failure can be contrasted with the professionalism of the main characters. Also it raises the possibility that whoever hired them isn't taking necessary precautions in planning and hiring. Earlier we heard Sam (De Niro) ask Vincent (Reno) if he was "labour or management" which suggests a theme of professional operators getting their hands dirty while their bosses play politics.
