I played this game extensively, and you can enable "realistic parking" in the traffic manager mod, which assigns parking requirements to buildings (visible with the traffic overlay). You can also disable the auto despawning of cars, which means you have to build parking lots for them (either with mods or the handful of vanilla parking lots). There's also DLC which provide a lot more walkability options, including bikes (and bike lanes) and the Plazas and Promenades DLC which has pedestrian only versions of the normal roads.
