The robber passes the same orange 60's Mustang in the first two robberies, even though they were supposedly in different locations. Additionally, traffic is stalled at both robberies, yet Jon and Ponch go past moving traffic to catch up to the robber.
As soon as Jon and Ponch begin to pursue the robber, the road footage changes from a three lane road with nothing on the side of the road to a four lane road with houses beside the road, yet when the robber is shown again, he's back on the same three lane section of freeway.
The yellow car crashes on the exit ramp and ends up facing the wrong way. Jon and Ponch park their bikes on both sides of the car. In subsequent shots, the motorcycles are in front of the car.
When the elephant is doing the standing trick, it is oriented 90 degrees to and some distance away from the side of Bear's cruiser. In the subsequent scene, it is in line with the car and sitting on the front end.
The spare tire removed from the trunk was bald (no tread). The spare tire on the car that blew after being changed still had tread on it.
Upon arriving and looking at the driver side of the truck and trailer, Ponch comments the truck's axle was broken so it could not be moved. A few minutes later when the elephant is used to move it, the truck's engine is running under load and the truck is rolling on all wheels, something it could not do if the axle were broken.
When the Cadillac finally stops, it is only a few hundred feet from the ramp upon which Jon and Ponch entered the freeway even though it had been clocked at 80 MPH and was shown at that speed for over 30 seconds. At 80 MPH, a car is going 118 feet per second, so it would have been over a half-mile away from the ramp in addition to the distance it took the motorcycles to overtake it.
Jon and Ponch stop to help Mrs. Abel change a tire on her grandson's car. With the car jacked up, Jon proceeds to tighten the lugs with the car still in the air. Of course the tires spins and spins. He then has Ponch lower the car and tells Mrs. Abel they're done. The final tightening of the lugs has to be done with the car on the ground. If the car was driven without doing so, the wheel would promptly come off the car.
Jon looks at his watch, which indicates 8:30AM. Jon tells Ponch to hurry up as briefing starts in 30 minutes, or 9:00 AM. Actual start time for Day Shift is 5:45 AM, so they would be more than 3 hours late.
Jon is able to remove the lug nuts with minimal effort. If they were that loose, the wheel would have fallen off the car while it was being driven, which was a concern voiced by the driver while Jon was changing the wheel and tire. Additionally, when Jon is shown tightening the lug nuts, he is turning the wrench in the direction to loosen them.
Bear arrives in a 1974 Dodge Monaco police car that has a push bumper on the front end. The elephant sits on a 1972 Dodge Polara police car without a push bumper. Older lower-cost cars were damaged instead of recurring vehicles to save money.
When Jon is talking to Leo outside of the courthouse, the lights and film crew are reflected on Jon's sunglasses while his sunglasses are hanging on his pocket.
When the Paramedic truck shows up to save the two people found in the truck, the side of the truck had the number 506... when our characters walked to the rear, the number 508 was now visible on the truck.
In the first few seconds pursuing the robber the first time, Jon and Ponch pass another CHP motor officer who is sitting in traffic in the right hand lane. This was reused footage.
As the robber flees Jon and Ponch into the parking lot, similar rubber marks on the road indicate the shot was made at least four other times.
When Norrison is leaving the jail, the microphone and wires are visible under his t-shirt.
Norrsion tells Jon it's been 4 years. Since they went to high school together and Jon was a year younger, this would make Jon about 21 years of age. In December 1977, Larry Wilcox was 30 years old. Jon Baker had prior military service before joining the CHP (he was a Vietnam veteran). If he served two years right after high school, he could have joined the CHP at age 20, but he would have to be on the CHP longer than 1 year to be a motorcycle officer and trainer.
The male victim rescued from the yellow car was clearly breathing, so there would be no need to give him mouth-to-mouth resuscitation as shown. Additionally, Jon say "They're afixiated!" instead of "They're asphyxiated!"
Getraer tells Ponch that he thinks Janey photographs older. The pictures of her that Ponch had seen were artist renderings, not photographs.
The robber avoids riding in front of the CHP cruiser that partially blocks the road despite there being more than adequate room for the motorcycle, yet narrowly rides between the CHP motorcycles.
Jon tells the Cadillac driver he was clocked at 87 MPH, but the speedometer shot of the motorcycle showed it was doing 80 MPH.
