Fast & Furious 10 should borrow absurd stunts from other action movies. With the recent release of F9, much of the commentary on the movie has centered on its utter disregard for realism, to the point of the series now more closely resemble a superhero franchise. The Fast Saga, having begun with street racing and stealing DVD players, has taken the slow burn approach over 20 years to get to this point, which is why it can get away with what would normally have been a very jarring (to put it mildly) metamorphosis.
With two more movies in the mainline series, it's still not clear yet exactly where the Fast & Furious series is going to go. Considering that F9 involves magnet cars, a rocket car traveling into space, and innumerable instances of Dom and his crew surviving the unsurvivable, the possibilities of where the franchise even can go now is getting more and more narrow. However, one solution to that problem is for the Fast Saga to look at moments where other franchises have gone overboard, and retrofit their basic concepts into the series.
For one thing, with space travel now in play, the Fast & Furious movies are way too far past where they began to return to the simple street racing of The Fast & the Furious, or even the earthbound albeit spectacular heist of Fast Five. At this point, the collective expectation of audiences for the level of outlandishness the Fast & Furious series has adopted is "How far can they take this?" The franchise, at this point, is now banking entirely on how much Dom and co. can thumb their noses at being bound by the laws of reality, so it might as well just keep turning the volume up all the way to the end of the road.
The franchise has essentially become the Jack Slater series from 1993's Last Action Hero, and the movie is full of moments like Jack surviving an explosion with only dust and debris to show for it that would fit right in with Fast & Furious logic. The series could also look back on its own history and recreate some previous absurd action scenes of its own at an elevated scale. Dom jumping a car across three skyscrapers in Furious 7 could now become an automotive zip-line stunt in the vein of Philip Pettit's wire walk across the Twin Towers (seen in 2015's The Walk). Furthermore, the movies the Fast Saga could borrow from don't necessarily have to be that ridiculous themselves either. If Fast & Furious 10 were to take some inspiration from the action scenes of Twister or San Andreas to pit the heroes against natural disasters like tornadoes or earthquakes, its threshold for going over-the-top could easily withstand that.
To take things even further, 2008's Indiana Jones and the Kingdom of the Crystal Skull delivered the infamous scene of Indy surviving a nuclear blast inside of a refrigerator. While this moment was widely hated by many, even leading to the "Nuke the Fridge" idiom as a parallel to "Jump the Shark", there's little to indicate Dom surviving a nuclear blast under similar circumstances would be pushing things too far for Fast & Furious. Whatever Fast & Furious 10 has in store, looking at where other franchises have gotten too out there and putting a Fast Saga spin on it might be the best rabbit it could pull out of its hat.
