That is where strategy matters. Try to carry more PCC and build post boxes near the area of the mission or campaign with chiral network coverage or use the postboxes that other players had build around that area. Just try to remember what post boxes you put the cargo. No worries about this cargo will be missing or stolen. Mules and other players cannot steal what you store in your private lockers, in the postboxes.
Yeah, this is what I noticed about this time about how everything is more separated by function.
Carriers are surprisingly capacious, 2 of them plus a bokka assisted backpack load = lots of cargo by foot.
Bikes are zippy and nimble, ideal for laying out the bones of zipline networks, postboxes and other structures that benefit from being placed intelligently.
Trucks have high capacity, but are relatively slow outside of upgraded roads, and generally work best when kitted out for the task at hand. e.g, battle mode, or full on roomba syphon mode. Yes, you can brute force them to basically use them for all situations off-road but your cargo will likely take a beating in the process.
Monorails are just awesome for mass transport of mats and vehicles, but being tied between mines and distro centres for the most part are mainly there to allow you to centralize materials/cargo at a given point for further distribution.
Magellan is the glue that holds it all together, but obviously you lose a lot of likes moving cargo using it. So the smart thing is to use it primarily to shift non-scored stuff like weapons and materials.
Ziplines though are the goto for speed and safety across any sort of terrain. It took me a bit to realize the utility of the alternative beam path because although making a parabolic connection between nodes is slower, its super useful on terrain that is blocked by a hill or some other obstacle that would otherwise require an extra zip to be deployed to complete the chain. For example there's a big permanent BT area between Pizza Guy and the Architect which can be crossed using only a couple of zips if you position it using the parabola mode, you just bunny-hop over the mountains that otherwise block line-of-sight.
