Factual error: In the opening race scenes, the cars on the track are out of date for 1989.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)
Continuity mistake: When they get to the bridge, Tej spins out a truck beside Dom then crosses the bridge, Dom and Jakob are still far away but Tej is already by the bridge.
Deliberate mistake: After jumping off the cliff, Dom and Letty's car rolls over violently several times and finally lands on its wheels. Letty sits calmly, safe and sound, not a single scratch or bruise despite not wearing her seatbelt and having survived by just grasping the handlebar above her head.
Deliberate mistake: During the chase with the mega magnet that attracts humongous armored trucks and all metal objects, surprisingly the people's watches, rings, jewelry, keys or belts don't move a single inch, thus allowing everyone to remain steadily on the ground instead of flying towards Dom's magnetized car. This allows for the hero to avoid killing innocent people, but it's all totally senseless.
