Mmm. The simulation engine as part of simulation any given zone, produces "trips" (I don't know how many or how often) from each zone, and figures out where those trips end up - successfully reached a useful destination, went too far and gave up, etc.
In SC2K the graphics do not depict individual cars or people, and I have no idea if in later games there is a correlation between individual cars and people and "trips" (or if trips are still used as mechanism in later versions - although from what people are writing, it seems they are).
