Last night, I sat down and thought about the Car Chase scene. I'm not sure if it's Joker's Semi and the Batpod, but that's what I thought about.
Somehow, Joker seems to be getting away in his ride, and he doesn't see Batman anywhere. And then all of a sudden, from a raised platform (or some sort), the Batpod comes whipping through the air and lands a couple of feet from the Joker's car. And then Batman sets 2 missiles straight at the Joker.
I know it sounds kind of idiotic, but you'd have to visualize a little bit. It came off as pretty badass. I mean, I'm sure Nolan will make it great, and from proclamations that it's the best car chase in movie history (or something like that), I won't be disappointed.
