Thanks for your answer but that’s not actually answering why people want to be so far away from their carrier all the time and “need” to automate it.
I explore with a carrier, I set it on its way while I go about my exploration. It runs out of fuel. I go to my carrier when convenient, mapping systems all the way, dump my data, swap ships and refuel.
The only real reason I can think of for wanting to do everything remotely is that you want to leave it in the bubble while you’re out and about doing something like PTN missions.
I do see how having to change ships is a pain, but not being within reasonable jumping distance of your carrier. And it’s something no-one has explained yet, just criticise those who think it’s okay as is.
I'll say two more things on this topic and then I'll probably resume just playing the actual game for a while
Firstly, to the motivation:
Given my particular situation, the next time I use this remote-fuelling capability might be when I get around to a dedicated chunk of exploring in the deep black, within a particular neighbourhood, and want my carrier around for a guaranteed ability to repair and cash in data, plus having the whole fleet around (e.g. canyon-running on newly discovered planets?). If/when I ever do this, I am loosely planning to move my carrier over there
in advance of joining it. Let's say I send it 40 kly. Spansh says that would need 82 jumps for a heavy carrier, using over 10 kt of fuel, so more than 10 on-board refuellings, and a total trip duration of 27+ hours of game play (perhaps 60+ when the servers are busy).
If I were to do that
without an alt I'd need to be on the vessel every 8-ish jumps to transfer fuel. If I instead get my alt to do it, I can enjoy the game as I please until the carrier is in position, then jump to it at 10+ kly/hour (I'm still a novice neutron jumper!), so after 4 hours of in-game time I'm with my carrier and can engage in the exploration. Of course I could explore along the way instead, but doing all of my exploration in "virgin-ish" territory would feel more valuable.
It's kind of the same story on the way home. Better still, I can jump back to the Bubble double-quick (e.g. if a new event happens,
like just occurred in Sol) and let the carrier follow in its own time. This frees up dozens of hours of my time for each of the outward and return trips. Not a minor motivation, in my book, and I'm likely to give it a shot and see how it works out.
Secondly, here's a question to those who think it's OK as it is:
If FD added a button next week to transfer fuel, but said you had to unlock the button for 20,000 ARX,
how would you feel about it? I think most players (including me) would be appalled, and I'm sure they'd be flamed all the way to Beagle Point for it

My point is that this button is already available to anyone who buys an alt. It's not even hard or all that much faff (but admittedly it's enough initial set-up faff that I've never yet gotten around to making the process slick). I don't mind the money (I can't recall how much I paid for the alt, so it was probably less than £10); it's just
odd that transferring fuel can't be done remotely but can be done with what appears to be an FD-sanctioned workaround that costs RL money. I suspect that not all players regard the cost of an alt as trivial.
