Factual error: When the multiple vehicles are chained together and latched onto the helicopter, the chopper starts lifting up hard enough so that most of the vehicles are off the ground with the lead one only touching by the front wheels. The driver then hits NOS in the car to super charge the front wheels. We see them spin on the dirt road and pull the other cars down bringing the chopper down. However this defies almost every law of physics. With the cars lifted up and the weight taken off the front wheels of that vehicle, and it being on dirt with no spikes, there's no way it would have the traction to pull the chopper down at all. It would just peal out in the dirt. (01:45:40)
Other mistake: Deckard and Hattie were children at the same time, with Deckard appearing to be no more than 3 years older than Hattie. Although Jason Statham is presumably playing a character younger than he actually is, he is still noticeably much older than his on-screen sister. Jason Statham is in fact 21 years older than Vanessa Kirby.
Continuity mistake: When Hobbs and Shaw are in the glass room meeting, Hobbs throws a chair that's next to the table at the glass towards the men on the other side. That chair lands on the floor near the glass, but when the camera pans after that, it shows Hobbs' hand on the backside of that same chair, and the chair is still at the table. (00:20:10)
Factual error: In the helicopter scene, the main villain yells at the pilot to climb. He then goes up and throws the pilot out and takes over. It is a common misconception that helicopter pilots sit in the same seat as airline pilots (left seat). Helicopter pilots sit in the right seat. He just threw out someone that wasn't the pilot.

Factual error: The grenade is kicked from its resting place and thus the firing pin is removed. 14 seconds later Shaw returns the pin to disarm the grenade, ignoring that mistake (which is already listed), a grenade's fuse is approximately 4 seconds. Much shorter than the 14 seconds shown on screen. (00:25:30)
