The Matrix Reloaded was crazy in terms of production, as they built their own 3 mile highway in the middle of the desert near California. The filming of that chase scene in the Matrix Reloaded took weeks to film, and I thought it was pretty well done. However, the CGI(computer generated imagery) of the agent could look bad at times, espcially when he jumped from a car's hood. Usually, they film these scenes in remote locations or pay the city have these streets closed for when they film car chase scenes.
