During the chase on the mountainside, the passenger's side window on the orange Mustang alternates between being opened and being closed. Also, after it rams into Mitchell's car, it loses a headlight, but later in the chase, the headlight is back.
At one point Mitchell gives the time as 24:17 hours. This is not standard military time notation as the day ends at 24:00. Times after midnight are occasionally used by some scheduling timetables but not for military/police time.
The main rotor of the police helicopter is turning much slower in the close ups than in the long shots; revealing that the close ups were shot on the ground or on a sound stage (the sound of the rotors is steady throughout the scene).
