The scene ended up in the trailer and inadvertently encouraged a bloat of fanboys to flock to their keyboards and pound out protests against the fake-looking CGI in the movie. But as Christopher Nolan has proved time and again, he doesn't mess with that shit if he doesn't have to.
No, what you are actually seeing there is a complete one-third-scale model of the Batmobile, the garbage truck and a large section of lower Wacker Drive in Chicago.
They stuck the two vehicles on a guide and smashed those mothers together. What you see in the film is the result.
Even the damn 180-degree move that the Batmobile pulls off at the end was done by a radio-controlled model.
So what about the climactic moment in that scene when they flip the Joker's 18-wheeler after Batman clotheslines it with a grappling hook? If that was a model, it was pretty goddamned convincing.
