Ponch has already placed the male motorcycle thief in the front seat of Baricza's cruiser, yet when Baricza drives up, the male thief is now in the backseat, and the female thief is in the front.
When Brent chases the remaining motorcycle thief to the middle of the grassy area, he stops his motorcycle and waits for the thief to either come his direction or go back in Ponch and Jon's direction. When he first stops his motorcycle, it's facing the direction he had been riding, but after a shot of the thief in the middle of the grassy area, Brent's motorcycle is facing the opposite direction even though it is clear that he has been sitting and waiting the entire time.
The water level inside the car doesn't change.
The Pinto went into the pool at a very slow speed. The impact would not have been sufficient to knock out the passenger as was shown.
During the first flashback scene where John first meets Ponch, because the shot of the motor bike going over John's car is done in slow motion, it is obvious that it's the stunt double on the bike instead of Ponch.
The information written on the squad room chalkboard regarding a basketball game between CHP and FBI and some math equations is still there from a much earlier episode.
The flashback with Ponch was supposed to be several years earlier, yet Jon is driving the same 1975 Dodge CHP cruiser that was currently in use circa 1977.
After Officer Brent Delaney pulls away from the botched traffic stop the lights are reflected by Ponch's helmet and the camera crew are reflected by his sunglasses.
In the flashback, a "younger" Ponch is seen fleeing and attempting to elude a "younger" Jon. That is a crime in California, and someone with that on their record would not be hired by the CHP.
Once Baricza arrives in his cruiser, Ponch proceeds to place the already handcuffed male motorcycle thief in the front passenger seat. Ponch should place him in the backseat, which is secured. From the front seat, the thief could escape, harm the driver, or have access to the shotgun mounted to the dashboard.
Even though Baricza already has two handcuffed suspects in his cruiser, he drives toward the action, ostensibly to get involved. This would be against procedure, as law-enforcement vehicles with arrestees or other non-law-enforcement passengers inside are not to be involved in further action that could jeopardize the civilians, such as chases. Baricza should wait until the other suspect is captured or call for backup.
