Curious... why did F7 get up there in gross without *that* much destruction? (sorry, I am not an aficionado...)

Likely because it was Paul Walker's final film.... (I am neither an aficionado as well hahaha)

They jump a car from one skyscraper to another... twice :P

That will do it!!! Maybe 1 skyscraper counts as 100 cars... that would push F7 up the x-axis
