The current logistic system is pushing logistical capacity where it is not needed unless told not to do that.
So every time the private open up a new farm, the entire logistical system of your empire goes into chaos, as thousands of trucks drive down to this newly constructed farm. This forces the player to continuously put traffic signs to avoid this situation.
1. The situation you are describing does not happen literally every turn, or even on the majority of turns. I'm fully in support of smart, minimal changes, like removing roads, which I pushed for on several posts, but let's not exaggerate the problem and pressure people with hyperbole. Even from day 1 with no patches the logistics system was never bad or hyper-tedious, just unpolished.
2. Make every private building only draw the resources it needs to operate. Think of it as an invisible, automatic, finely tuned traffic sign. Problem solved. For public assets, you built it, it's your problem to manage it.
3. The above improvement, coupled with removable roads that we already have, and maybe 1-2 new expanded / refined UI logistics filters and job is done. This system does not need drastic changes, or even very many of them.
Well that "invisible, automatic, finely tuned traffic sign" is the "drastic change" the entire debatte is about and what we hope to receive.
