Of course I can. When I arrive at the station.
I am sorry, I think I don't get your point. How can you take advantage of any available gameplay when you are busy fetching your other ship? This time frees up with ship transfers, even with non-instantaneous, which is why I call it a time-saver. Calling it a time sink only holds true if you compare it to the possible future with instant ship transfer.
Whether or not it's an improvement in either case isn't the point, it's how instant transfer impacts on your game and your fun.
Actually, that's not the point I was talking about when opening this thread, but I can go with it for this discussions sake.
It doesn't, because you can ignore it, or replicate delay if you wish. You clearly appear to be someone who likes playing multiple aspects of Elite, so you can do that to pass the time. Not everyone plays the same as you though.
I think here is where I fundamentally disagree with you. I want ship transfer! I want it very much, I even opened a thread requesting it over a year ago, if memory serves. So I don't want to have to compensate a implementation I conceive as lackluster by self-imposing game rules that are not in the game. As soon as something just slightly competitive - like Powerplay or a CG - comes into play, I can't even afford to self-impose this delay upon myself if I want to stand a chance against other commanders making use of instant transfer. So yes, I think having instant ship transfers will indeed impact the fun I have, even if I'd go with self-imposing delivery delays just for me.
This is why I think cost is a better restriction than time, sliding based on ship cost. Pitching cost at the right level that makes it affordable but not spammable, giving freedom and access to the majority while preventing abuse (and possibly place caps on amount of cargo that can be transferred, if at all, and absolutely no UA/UPs allowed to prevent bombing without effort).
This is where I have to respectfully disagree again. In-game money rarely works as a balancing factor, because it loses value so fast, and doesn't mean anything to some commanders who more or less used every exploit ever found in the game to become billionaires over night. Time, on the other hand, can't be bought and is of the same high value to everyone.
