Dude raises a ton of points that aren't exactly relevant to the chase scene, or that I feel were intentionally used for good effect. For example the orientation of Dent in the back of the truck is not actually important information because the only thing his presence there is meant to convey is "he's in the truck" and "he's getting rattled as the truck gets hit." Knowing where the truck got hit by the orientation of how Dent is shaking around is pretty "who cares." Hell if you want me to get all film critiquey it's likely that they were intentionally showing Dent at an angle that doesn't capture the whole sweep of the back of the truck to help induce a sense of panic and confusion-- if you can see the whole terrain back there the scene feels more controlled. It's also possible they made the shots zoomed in on just one to make it feel more claustrophobic back there.
Basically what I'm saying is "being hard to follow" can be a tool to make the scene more effective. And it's clearly something the Dark Knight does intentionally at times to create a feeling of panic.
I couldn't get more than halfway through it. I think the only good point he brought up was the random third cop car showing up.
