When Bruce closes the hood on the old truck is does not close completely but it is fully closed moments later when it emerges from the garage.
The 280ZX had not passed the other two cars behind the ramp car, yet when the scene changes it is now ahead of them and in the same lane.
Poncherello accurately counted 5 men including the Sheriff outside the store, and 5 including the Sheriff were seen going to the store. On the front view, 3 are seen by the Jeep, then Poncherello says there are 2 covering the rear, and Nelson says the Sheriff went back to his station, which adds up to 6 men. When the Sheriff returns with the tear gas, one of the original 5 are with him, so there could not have been anyone at the rear door.
When Poncherello and the girls first come into the garage, there is a lot of tear gas present even though he closed the door. When another round of gas is fired into the garage, the prior gas had disappeared. Likewise, when the first Jeep leaves to chase the truck, there is a dense cloud of gas at the garage door, yet seconds later when the second Jeep leaves the gas by the door is nearly gone. The thick gas returns a few seconds later when Bruce Nelson and the girls leave the garage.
When the Jeeps begin to chase the truck on the road, it has changed into a regular car.
Since they are county-level agencies, Sheriff's offices in California are named for the county, not the town in which they are located.
Even with 20/20 vision, both Poncherello and Bruce Nelson were too far back to read the license plate on the stolen car.
A minor crash would not cause the truck to explode as shown.
California has exactly 58 sheriffs, one for each county. Although there are sheriff's substations located throughout the state, these are manned by sheriff's deputies, not by the sheriff him- or herself. Since Lone Canyon is supposedly 75 miles south of Los Angeles, it's in one of the following counties: Orange, Riverside, or San Diego. All three are very large counties (as are most counties in California), and their main sheriff's stations are located in major cities. In short, it's impossible that Sheriff Bolt is actually a sheriff in California.
The ramp car frequently used to launch cars into the air appears and is rear-ended by the 280ZX. The ramp over the rear window and the roll cage inside are visible as Poncherello rides by it.
When Poncherello spins out of the truck to block the road, the film is reversed, as he is on the passenger side of the truck.
When Poncherello is escaping in the truck on the dirt path, it slides and the tire sound is that from tires on pavement.
The southbound bus that drops off the girls has a destination of Fresno shown on the front. Fresno is in the opposite direction the bus was heading.
After it runs off the road, the Jeep carrying the Sheriff goes in the wrong direction to catch up to Poncherello.
Juniper is at least 11 hours away and on the other end of the state from where Poncherello and Bruce Nelson were located, yet Bobby Nelson and Linahan make the trip in a short period of time during the same shift.
There are a couple of gross time errors. Getraer's squad works a daytime shift, which usually begins anywhere from 6 AM to 8 AM. Poncherello and Bruce Nelson apprehend a stolen car and assist with a multi-vehicle crash, either of which would require them to be out of service for a couple of hours, yet they still make it to the briefing. They are then shown arriving 75 miles away in "Lone Canyon" by 11:30 AM. While that is feasible, Bobby Nelson and Linahan are at the same time shown in Juniper, which is 10 hours and nearly 400 miles away from Los Angeles in Northern California close to the Oregon border.
When the CHP motorcycles are stolen neither Nelson nor Poncherello take any law enforcement action. While Poncherello correctly states they are outnumbered 5 to 2, he fails to take into consideration both he and Nelson carried firearms. However, this would have required them to draw and firearms, something only done once in the entire series by Officer Baricza.
Bruce Nelson fails to use CHP 11-codes when calling in the first crash.
Captain Burke has his grandson with him at work, which was highly implausible as he would have had to ride in a CHP police vehicle to get there, which is prohibited due to liability except for certain occasions. The notion he could not take him to a meeting at city hall was likewise implausible. Since both locations were government buildings, there was no difference between the two for the child to be accommodated. Finally, under CHP policy he could not farm the child out to a subordinate such as a Sergeant since that was not a job duty of the subordinate.
When using the motorcycle radios, Poncherello states each time "Come in, LA 15 7 Mary 6." Even if he was within range, the proper procedure would be the one he had always used: "LA 15, 7 Mary 6."
Bobby Nelson is shown talking to Getraer on the LA frequency from Juniper. Juniper is about 400 miles away from LA, so his radio would not work on that frequency at that distance. Nelson would have used the CHP "Amber" frequency for Alturas (60), which had a tower 12 miles away from Juniper and was dispatched out of the Susanville, CA station.
