@Smiles2us So I just watched the movie. The car chase was indeed "Shark" having a nightmare. So I guess that when he gets flashbacks of that scene at the end of the movie, it's not really him taking revenge, it's probably just him being silly (just like the rest of the movie is).
OR just that he tries to take good aim at the car like he did in his dream. I didn't show it in my video, but before the car gets pushed off the cliff in his dream, "Shark" had stepped out of his car to shoot at their enemies, before realizing his gun wasn't loaded (just like at the end of the movie XD), and stepped back inside.
ps: the movie was good :3
