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.
Suggested correction: I don't know what air brakes you have used but the very nature of air brakes means that low pressure means they can't work. If you have no pressure in them, how are you supposed to press the brakes? I have personally driven hundreds of vehicles with air brakes (I am a truck driver by trade) and can tell you this is a fact. All that happens when air brakes lose pressure is a warning light on the dash and an alarm sounding in the cab, one must manually slow down the vehicle at that point.
I respect the fact that you drive a truck, but my dad has been a master mechanic for more than 50 years and he is the one who pointed this out to me. Depending on the system, there are various fail-safe systems that will engage the brakes during an emergency loss of pressure. Plus, a simple Google search led me to several examples of these systems.
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.
