Factual error: It is not possible to have a conjoined twin of the opposite sex. They are similar to identical twins, which are always of the same sex, in that they are formed from a single zygote. In the case of conjoined twins, the zygote fails to divide normally.
Factual error: Dwayne Johnson is pursuing a thief. He gets into a Porsche Taycan and pushed the start button, and he can drive off. But you have to have the key fob in your pocket or bag. Porsche explains: "As long as your key is close when you grab the door handle, the system automatically checks the encrypted access code on the key. Once your code is validated, the door will unlock, and you'll be granted access to your vehicle." Dwayne had no fob, as the car was just parked.
Factual error: In the sex scene, when Adam Driver pins Lady Gaga to the wall, the map of Milano on the wall says "Mailand." Now there are parts of Italy where they speak German, but Milan is not part of it, so it's highly unlikely that they have a German map of the town (which wouldn't be produced in the German-speaking parts either). Since it's in her father's office, the map cannot be from Gucci's mother (who happened to be of German origin).
Factual error: There is a "Covered California" sign in a window. The referenced health insurance exchange did not exist during the 1990 time setting of the movie. (00:20:58)
Factual error: In the opening race scenes, the cars on the track are out of date for 1989. The race car used by the aggressive driver (#23) who causes the fiery accident that kills Toretto senior is based upon a later model 1997-2002 Pontiac Grand Prix. The race car that Toretto senior is driving is based on a 1995-1999 Chevy Monte Carlo. (00:01:00 - 00:04:00)
Factual error: The Sheriff's car had "POLICE" written across the rear end, but with the exception of Allegheny County, deputies in Pennsylvania do not have police powers. They are County employees who carry out court orders (e.g, serving warrants and subpoenas) and work in court houses keeping order. They also transport prisoners and issue gun permits. It would be atypical for a Deputy sheriff to do routine patrol like Deputy Myers was doing. The sheriff's car should have had "municipal" or government plates. (01:16:18)
Factual error: After Ressler tells McChesney he wouldn't be surprised if one day she's tracking down sequence killers, McChesney replies, "Not sequence killers. Serial killers. That's what they should be called." But it was Ressler who claimed he coined and is often credited with coining the term "serial killers" (at least in the U.S). ** After showing pictures of some of Bundy's victims, Ressler is shown and it is pointed out, "He [Ressler] is credited with coining the term 'serial killer'." (1:31:30). (00:26:40)
Factual error: Unless left in the vehicle (not the case here), towed impounded vehicles do not have keys. Moreover, lacking keys, a valid registration, possibly proof of insurance, and new plates, vehicles bought at a NYPD auction are to be TOWED away. A newly-purchased auctioned vehicle, such as the Navigator in the movie, is "ticket-" or "citation-ready", not ready to be driven on the streets.
Factual error: At the beginning of Quintet, a modern Manhattan skyline is visible in the distance not a late 1950s skyline. Also, the view is consistent with the Paterson, NJ filming location, not the Upper West Side.
Factual error: When the hackers take out Zagreb, Croatia, one shot shows the effect on a train in a subway station. Zagreb has no subway.
