I’ve begun noodling around with turnaround services, starting with cleaning trucks. What I’m noticing is that the trucks won’t unload at the depot until they’re 100% full. This leads to trucks showing up to a stand already near capacity, start the service, then have to leave for the trash depot. It would be useful to have a threshold (player adjustable perhaps?) where once cleaning service is done, if the truck is above a set capacity it will unload at the depot instead of just returning to the garage.
Come to think of it, do fuel trucks exhibit the same behavior in reverse? It might be a nice feature to have a tweakable slider for any service vehicle to refill/unload according to management’s preferences.
