No, Steve, just no. The roadtrip a) establishes why the mob would hire the Joker (he knew what was going to happen before it did), b) is one of the key components in how Nolan conceptualizes Batman and Joker as opposite sides of the same coin: Both function outside of the law, both are dedicated to overturning the established order (the difference being that the established order Batman tilts at is the tacit agreement between cops, politicians, and organized crime to allow rampant corruption in Gotham), and c) reinforces the idea that, in operating outside the law, Bruce Wayne has put himself on a slippery slope. Plus, it's just a kickass sequence. And I like that, on the one hand, I was happy to see that smug money laundering sumbitch get what was coming to him; while on the other hand, I was disturbed that a police commissioner and district attorney teamed with a masked vigilante to blatantly violate international law -- that tension is intentional, I think.
So, the scene simultaneously advances the plot, buttresses the movie's themes, and delivers some enjoyable action. What more can you ask? It's sequences like the roadtrip that make
The Dark Knight significantly better than nearly every other superhero flick ever made.
