What sort of chaos? Saving up to 15 waypoints (what is roughly max number of jumps on full tritium depot) on the server and update a record once a 20 minutes? Even if it would be 20k of carriers (peak number of players) it could be run on Raspberry PI I guessIt's done that way intentionally to prevent the chaos that would be caused by carriers jumping en masse non-stop every single second. Bad enough they have to compute all the jumps that every ship in the game makes. To allow carriers to simply go on autopilot all the time instantly would be a disaster.
Anyone wishing to travel far (while being offline) now just need to go to Discord and find a FC owner to join the trip. Not everywhere, but most active destinations like Colonia, SagA etc. No one complaining about that.What's more, it would give carriers an unfair advantage over long range ships that can travel faster and render them completely useless to the game, which would have caused such an uproar that many people would have simply quit playing altogether.
And if someone would deside to travel through the systems not visited earlier it could be a set of random events on route which would interrupt the process. Something based on the skill of NPC crew (another feature to add). So it would be less predictable in comparison with "manual" variant, but still good way to avoid the need to get back into the game to schedule next jump every half an hour. And this could provide a "content" for FC owner to make the travel more entertaining. Or alternatively one could see and buy exploration data (via GalMap, almost existing function) and construct more predictable route (with less chance of random events) through the systems visited by other commanders earlier.
