This sounds like a waste of time and effort waiting for your drones to fly 100km.
On top of that, unless you’re able to kill the Hauler in time, it’ll just warp out since you don’t have tackle on it. This means you’ll have to scan down the hauler (and whatever defensive fleet is there), warp to them, launch drones and wait for them to slowly travel 100km again, and kill the Hauler. Finally, you’ll have to wait to pull the defensive fleet away from the wreck so that you can loot it safely.
Unless you have a video that explains exactly how it’s done, I think it’s a waste of time.
