At 1:41:25, when Vin Diesle is confronting Jason Momoa on the freeway, as Momoa holds Jordana Brewster hostage, there's a quick "shot, reverse shot sequence", switching between cameras recording from the front, and back of Momoa. From the front, Momoa has Brewster's arm twisted behind her back. with Brewster's elbow tucked behind her. But when it changes to the rear camera, Momoa has a totally different grip on her, with Brewster's elbow up in the air.

During the car race when Dom saves Elena's sister, the black charger and her yellow car are parked right next to each other when he pulls her out of the car. Then they show him gazing down the street from inside his car at the yellow car she was driving and it is a distance down the road. He never got in his car and closed the door when he was shown gazing down the road at the yellow car. It also should have been right next to him.

Lifts cannot fail in the way shown. The instant the tension in the cables drops the brakes engage and the car is then held in place by it's own weight. The lift would have dropped a few feet at most and more likely only inches.

No passenger airplane has a bomb tray-type opening in the fuselage.

Even a one-ton bomb rolling down the street cannot cut through the chassis of a bus, separate it in two pieces and continue on its way.

While appreciating the merits of Artistic Licence, one sometimes balks at egregious examples. (At ~0:22:50.) Landing on top of another person does not save you after falling many stories.

In Japan, they do not sell Hyundai or Kias although the company is a sponsor as you see them throughout the Japan scenes.

A car door would not be thick and strong enough to protect from a bullet shot from an marksman rifle, even at such a distance.

A marksman rifle is only as potent as the ammunition that's loaded. In this case, low powered, as evidenced by failing to penetrate either the ballistic vests or the car door. (01:43:43)

When Dom is harpooned by the two helicopters he is driving a rear-wheel drive car. They lift the rear wheels off the road yet he is somehow still able to overpower them. Once his rear wheels left the road there was nothing he could do, he would have just been a passenger.

The Dodge Charger Daytona SRT Banshee is not only 4WD, it has electric motors on all four wheels. This one has been altered to look like Dom's regular ride.

The bomb in the truck in Rome is described as "a DM-79 subnautical high yield neutron mine". Neutron weapons are designed detonate with a massive burst of radiation with a lower (relatively) explosive yield than a conventional nuclear weapon. So when the 'mine' detonates in the Tiber anyone near the explosion, including Dom, would have been exposed to a lethal dose of radiation.

Not lethal at all. Water is a very effective shielding medium against neutrons. Afterwards, a thorough shower, like James' and Honey Ryder's.

Despite entering the house to search for Letty and B and "need(ing) them alive" the paramilitary use real bullets.

It is unlikely that any paramilitary force anywhere would agree to breach with blanks in their weapons.

No one heard the helicopter approach the site of the accident and two agency personnel get shot without reacting to the potential threat.

They reacted. They fell down.

Pulling one cord behind a random desk shuts all the lights off...

In the bar fight scene, to end the fight, Brie Larson's character shoots a shotgun in the air. You can clearly see her index finger is underneath the trigger guard making it impossible for her to shoot the firearm without a trigger pull.

The bomb rolls downhill for almost 8 minutes. The elevation of Rome varies between a maximum of 13m above sea level and 120 metres. There just isn't enough hill for it to roll down.

Not one single guard has a regular hand gun to shoot if their "remote controlled" automatic guns bugged...
