I really love the inner city traffic, you created by setting different land use, buildings of same use grouping together and citizens moving home/work/home/shop/home/leisure. imo this is a very smart and entertaining feature. it creates a minigame within the game. one could neglect all other apsects of the game and just focus on intra city traffic. and i currently got a hang on it. observing the pedestrians, figuring out the best routes, etc, etc.
