When Jon parks his motorcycle in front of the truck, it is roughly parallel to the road, yet when he is seen getting off his motorcycle, it's almost perpendicular to the road.
When Jon is watching the skydivers, there is one blue parachute and two white parachutes, one of them with blue flags. Yet when the skydivers actually land, the chutes are black, rainbow-colored, and white with red flags.
The runaway truck over a long distance is completely implausible as all the driver needed to do is turn off the ignition and friction combined with engine braking would stop the truck.
The ramp to launch the cars behind it is visible on the green Pontiac GTO after the stolen truck blocks the road.
When Bates and Getraer begin the pursuit of the truck cab, the patrol car they're in is a 1975 Dodge Monaco. At the conclusion of the chase, the car turns into a 1973 Dodge Polara.
In the final chase, the stolen trailer is reported "southbound on Western, north of I-10," yet the chase quickly proceeds to a rural, hilly area. The end of the scene is filmed nowhere near Western Avenue and the Santa Monica Freeway (I-10), and there's no way the truck could have gotten to this area so quickly.
Lt. Bates is shown to be a strict follower of regulations, however when he and Getraer are on patrol neither of them are wearing a seat belt.
When Jon calls in the trucks the and Grossman are following, he (Jon) says they're "two white semis," yet only the first truck is white. The second one is blue.
