I don't go into these movies expecting them to be 100% realistic, but up until this movie, a lot of what's pulled off SEEMS like it could really happen. The entire Vault heist and chase sequence in Fast Five is a prime example. Couldn't happen, but it was done so well that it seems like it could be be pulled off.
There was a scene in Fast Five similar to Rock jumping from the truck to the car early in this one, but in this one it seemed way more unrealistic. Maybe it's because the drop drop down was a lot more. The whole tank scene was really cool until Vin Diesel saved Letty. I was like, "You've gotta be kidding me."
And if that wasn't the longest fucking runway I've seen in my entire life lmao.
