Factual error: Although it's a commonly used movie trope, cutting the brake lines on a bus would not produce the effect seen in the movie. Buses use air brakes, which by design, can operate even with substantial loss of pressure and often engage automatically if there is too much pressure loss.
Factual error: During the first scene of the bus sequence, it shows a 1 California Bus operating nowhere near the actual 1 line in real life. Throughout this scene, the bus then teleports to the middle of downtown.
Continuity mistake: The right side mirror on the car is broken off by a tree in the maze, then returns. (01:06:20)
