I'm not sure how well that could work when I want industry to have the same depth as C:S. Like, if a commercial building is expecting a shipment from a specific industrial building two cities away, the location of that truck needs to be tracked through its entire journey. I suppose it could be possible for a server to track something like "The last 10 trucks to enter my area at location A and leave my area at location B took an average of C minutes, so just assume any path finding through me will take C minutes and don't track the individual trucks" But then what happens when some zooms into that server's area while a truck is partway through its course? How do I simulate a traffic jam occurring after a path has been planned if I'm abstracting the individual vehicles away?
