I know it's pointless...

Dude, you're analyzing it too much - it's just a movie. It's meant to be fake and look fake, simply for the entertainment of others. I'll try to be a bit optimistic though about some of the points you listed!

1) Yes it was a really long runway. I think what made it appear this long is that there was about 5 fights happening at the same time, and they couldn't show them all at the same time (obviously) so this is why it seems that longer. I'm sure the producers wanted to be realistically shorter, however this would've made the climatic scene of the movie shorter, which would've been disappointing too. Catch-22 situation.

2) The reason is that Dom is about 2.5 times bigger than Letty and to them clash in midair and then plummet straight down wouldn't have been realistic as Letty's small frame wouldn't be have enough to stop Dom's dead in midair. Again though, very unrealistic.

3) No argument.

4) A convoy for the military would be much bigger than that (yes). I think the reason the chip was stored inside a tank, inside a truck, in a convoy, was for security purposes. No one seemed to fathom all 3 elements being breached.

5) I agree, but after their conversation, I don't think that Dom was too concerned about Shaw's threats as he was focused on getting Letty back. It was almost as if they agreed to disagree.

6) No argument.

1) The other guy was right and I had to tell my friend this too. The runway was nowhere near as long as it appeared. It was probably nearly a mile long, about the length of the longest runways in the world. There were many fights going on at the same time so it seemed like a longer runway.
2) It's all in the physics. Letty loses momentum the longer she's in the air. She's not being propelled forward near as quickly as she was to begin with by the time Dom slams into her. Dom's much larger weight and momentum slam them to the side, right onto the other side of the bridge.
3) I think it was a bit of cinematic license used to show that Hobbs was officially on their side, far more so than he was at the beginning of the movie. Plus he may have had confidence that they could still stop him before he got too far away.
4) I'm sure he didn't see a tank and a cargo plane coming. He probably assumed it would be transported to the U.S. for deployment though.
5) He underestimated Shaw's connections, just like they did with Riley. Since Riley didn't reveal herself as a traitor until after they had captured Mia, there was no reason to assume that anyone but Hobbs knew where Mia and Jack were.
6) He probably had Mia captured hours before he was captured. That's why he was so confident. It was an insurance policy to bail him out in case of emergency. He knew Dom's "code" would prevent him from making any other decision other than to release him. He basically manipulated him, and it was actually pretty clever. Shaw made one mistake though. He gave them a way to stop Mia from being killed while still going after him. That's what really did him in.

I have to say that I agree with virtually every argument made. Does this change my feelings about the movie? Nope. I don't know, maybe I'm part of a group that can allow myself to suspend belief on virtually every preposterous stunt a film can throw at me, AS LONG as it's entertaining. If it starts failing to entertain, the suspension of belief is no longer worth it. I know there are other groups that can't take it, entertaining or not. I can understand where this group is coming from too, it just means people have their differences. Nothing wrong with that. In the real world, I definitely consider myself a realist. Anyway, the main reason for this post is to address #2 and #6.
Anybody who thinks #2 could ever turn out like that is either fooling themselves, or just need to brush up on their mechanical physics. Trying to measure what would actually happen in that scene involves things such as time-displacement, velocity, and acceleration, then parametric equations involving those vectors for 3-dimentional objects. And that's only if the two objects were moving at a constant rate and direction. What I just said was all just the tip of the iceberg. Then you throw in things like their trajectile path, aerodynamic drag, the acceleration due to gravity, and weight(since mass is independent of gravity). Let's not rule out mass, however, because even though gravity is not affected by mass, mass still plays a huge roll in just how hard they collided into each other. If Bruce Lee was still alive and you asked him how his punches were so effective, he'd probably tell you force = mass * acceleration. The faster the object moves, the more force behind it; and likewise, the higher the mass of the object, the more force behind it. I doubt they'd have even been able to grab onto each other (rather than bounce apart) with that measure of force. Even if they had been able to do that, my guess is that they'd fall between the bridges, but closer to Letty's side. I say this because Dom probably had more initial velocity than Letty did, and he has a much higher mass. Take all that other stuff mentioned earlier, his velocity and mass would still not be enough to take them to the other side. Lastly, even if they had made it to the other side, at the very least, Dom would have been critically injured (or dead from internal bleeding), if not both of them injured.
As far as #6, I got the impression that because they didn't know where Mia was being held hostage, they needed to let Shaw and his lackeys go so that they would lead them to her location. Still, they would not have let that chip go just for her, no matter how angry it would make Dom or Brian. Whatever, I guess, if it had gone differently then I wouldn't have been able to watch all that awesome action at the end. I have enjoyed most of these movies, except 2 and 3. I don't remember if I even saw 2, and wasn't interested in watching 3 at all.

The last one is actually quite believable. He simply left orders telling his men to kill Mia if the didn't hear from him by a certain day/time. At least this is what the good guys probably think. With Riley on his payroll, he could contact his men whenever he wants.

@ phixzet - THANK YOU!

That's nearly identical to every single one of the problems I had with this film.

Yes, I understand the Fast & Furious films are not known for their thought provoking plotlines or character developments.

But c'mon... this god awful piece of cinematic fecal matter went from completely ridiculous to absolutely absurd faster then the cars they drive.

I had to get up and walk out when that scene where bad guy Shaw (played by Luke Evans) was captured and blackmails Vin's crew. Then the Rock pulls out his gun and forces the foreign military guys to release villain Shaw.

WHAT?!?

They already stated that the device Shaw wants can potentially kill millions. I guess if you or your family is one of the millions being killed it doesn't really much matter to the Rock whose job it is to arrest Shaw for that very same thing.

7) At the end of the movie, the crew see Dom crash his car. He may be bleeding out and in need of immediate medical help. So what does the crew do? They wait and stare at the burning plane like a bunch of fools. Sure enough, Dom walks through the flames (instead of simply walking around the burning plane). The crew also doesn't seem to care about Gisele. A sane person would immediatly ride around the plane at the end of the movie and check up on Dom and Gisele.

Yes, the runway must have the longest in the world. I liked the film, but all the fighting made it rather boring for me, it just went on and on. I gave up in the end and just asked my husband what happened. I have loved all or most of the others, but this was a bit cold for me.

its a fiction anyway, but I dont really like it.

THRILLER IS MY FOOD!
