Continuity mistake: Sheriff Buford T. Justice gets out of his car and leaves the door open. A few moments later, we see a different shot of the car with the door closed. Then a truck drives by and tears the car door off which is open again.

Factual error: After mounting armor in the bus they are approaching Phoenix on a two lane highway from the northwest. When entering the city they are shown coming around South Mountain on Interstate 10 from Tucson from the south.
Factual error: In the scene where a politician is making a televised speech away from the studio, the camera is a vintage RCA black and white TK-12, but the camera monitors in the van are all in colour.
Factual error: Donald Pleasence's character makes a left turn at an intersection controlled by a traffic light. The camera pulls back and reveals an Interstate highway shield on the road he turned from. Interstate highways never have at-grade intersections controlled by traffic lights; they are designed to be non-stop routes with access to side roads available only through ramps and grade-separated interchanges.
Continuity mistake: When Evel Knievel goes to the insane asylum to break his buddy Will out of the institution, he crashes through the front door with the Stratocycle, breaking off the airplane-style wings on each side of the bike in the doorway. In the next shot, as he rides down the hall, the wings are still intact.
Visible crew/equipment: After Bruno Ganz shoots the man in the train station he walks out onto an open-air concourse. In the overhead shot facing him, we can see the strip of duct-tape on the ground marking the spot where he is supposed to stand.
Other mistake: Susan gets upstairs as Iris shows her the room. She manages to miss the naked woman lounging in bed - watching the scene, it's an impossibility. It might not be the proverbial elephant, but it's just something so very unusual and conspicuous in the room, in a spot perfectly in line of sight that it makes no sense Susan would miss it and be surprised by that later. (00:08:20)
Continuity mistake: After the Abebo murders, tempers run high at the meeting of the clan. The sinister Sakoda accuses the one raising objections to be a wimp, and the guy slams his fists on the table. The president of the meeting says "stop it"; Sonny Chiba is leaning forward with both hands, but in the next shot he has one hand in front and one in the back. (00:20:00)
Continuity mistake: When Regan and Bianca first jump on the bus to escape the hitmen you can see through the windows that there are only six people on the lower deck, but when the scene changes to inside the bus all the seats are full. (01:00:24)
Continuity mistake: When Vivian crashes the VW bug into a tree in the park, it shows front hood damage on impact. Moments later, after some exposition, she backs out, and drives away with the hood intact.
