Stations are everywhere and you can get to them quickly.
Except if you're in a Trident. There's nowhere to dock one of these things.

Yes, that is true, but it's a temporary situation. The devs intend to add more docks, they've just been taking their sweet time about it. Meanwhile, there are plenty of empty sectors. You can logoff while drifting as well, so that if somebody does find the sector before the ship has been removed, it will likely be fairly far out, possibly beyond targeting range.

If you guys want to make my ship float around for a while when I want to log off, fine with me, but let me close my client cuz I don't want to personally wait that 5 minutes.

Yeah, nobody is asking for the pilot to hang around, only for the ship (and any cargo therein) to persist. And turret gunners, when applicable.

I still insist that the /logoff command should take an optional argument.

/logoff now - Leaves your ship in-game for the duration of the timeout, but immediately logs out the game client.
