Currently we have one big cargoroom in vehicles like the Sugarcube, the Explorer, Truck or Trains. Remote miners and small factories will never produce enough to fill that up, so why not using it for other stuff?
Setting contingents for how many item slots will be used for a resource or item would be efficent and effective. You could run one automated Explorer or Truck for a bunch of Truckstations, filling the cargoroom partly with a fixed amount for resourses or items, no matter how much of it is in the Truckstation.
Combined with smartsplitters you will gain more control over the goods that are 'running around' in your factory, and more control ends in being more effective sooner or later.
