Could you also make it to were full pickups and trucks that can't unload (due to destination being full aka a building/storage or a filled dumping designation) also use the parking spots instead hovering around their assigned building/dumping spot (when dumping loose materiel) or stopping in place if something gets canceled or full?
It would be great for seeing how many are full in a mine (instead of clustered around the tower) or consolidating them when a dump designation gets canceled or fulfilled (before it could finish dumping its load).
