Maybe I understood you wrong - let's see about that. If I got you right, you want that someone can go from the current star system to a destination star system in one go, let's say Deciat to Maia - which is one of the first challenging journeys for a newbie - like 20 jumps normally, let's further say 6 minutes each, so it takes 2 hours - and instead of this being an experience for the newbie, he can just go and watch a movie for 2 hours and arrive in Maia - same again when he has gotten meta alloys and is on the way back to Deciat - again 2 hours for another movie and no danger of being ransacked by pirates (and there are some, who want those meta alloys). So instead of 4 hours of interesting game play with some excitement, that newbie would be 2x2 hours watching videos - nah, I don't see FDev implementing that - that is not a win-win at all.
And what if I want to travel from the bubble to colonia - will I be just a couple of days offline then, while my ship is traveling the distance? Sure, you would have to refuel once in a while - but why not automate that as well then?- Why not remove pretty much all tedious stuff from the game?- Oops, there is nothing left anymore - even a lot of the fights are just of the Sun Tzu type of fights (already won from the start), so why not automate them as well - what is left from the game, if we follow that path to remove everything what is a little boring or tedious?
I see why you want that from your personal perspective, but I don't see it benefitting the game in a whole. It's afk travel in the end, you are not playing the game for eventually hours or days, while your ship is "playing" the game for you. We have more than enough stuff already, which makes these travels very bearable - like refueling around a star, supercruise assist does that for you - or travelling inside a star system - supercruise assist does that for you as well - or docking and even leaving a station - docking computer does that for you - well, why not give me a win-game button and I don't have to play at all?
Having to travel in the way it is makes you want better modules for your ship - so it gives you something to thrive for, a goal to achieve, which will make your life in the game better. But to really want that, it takes that "unbearable" moment of having to travel in a tedious way to even want to change that. Why would I even want a better FSD, power plant or other elements which make my ship better, if I can just watch a movie while my ship is warp-snailing through the galaxy on it's own - and this is what it becomes then. Deciat to Khun f.e., in my travel sidewinder I could make the distance in a single go without having to refuel - that is an hour, where I could just do something else (using your suggestion) - which is "not playing the game" - why do I want to play ED again?- Ah, space travel, sci-fi future - which I'm not experiencing in the end, because I will be afk traveling - no really, that is not the way.
