They don’t, just closer hubs I was using as example. Some of my items were placed in the market along the trade route. I deemed it not worth hauling it for just a few million isk. I used Eve Tycoon website to formulate where items could be sold in bulk at better locations. Some were sold off in Dodixie.
I was using various T1 haulers: Tayra, Bestower, Epithal and Miasmos. Not one got hit. I am rich with isk and buying ships now. After they all get blown up, it will be time to recycle; Farm → Haul → Buy Ships → Explode, rinse and repeat.
I play that version too, but it is not made by FC, and it is not online multiplayer.
Available for Windows and Linux native client Endless Sky is on Steam too. A very addictive game free to play offline.
Back to the topic, it might work for others, but being mostly a PI farmer, I lose tax money when I take my goods through customs some as high as 15%. Then you ask someone else to haul it for 5%, and top it off with a broker fee and more sales tax. You tend to lose between 25 to 30 percent, to game taxes and fees, just moving it.
