just off the bat i am putting it out there i am not neccesarily against AP (though would MUCH prefer it was an npc crew person acting as co-pilot)... but i am currently neither 1 way or the other.
however just in regards to the docking computer.... imo FD were pretty good with the DC implementation.
it uses a slot, adds mass, and most important of all is FAR from the most efficient way of doing it, and can be dangerous if you go AFK whilst using it, esp in open. my mate i play with often uses one, and I can constantly get in, unload and be getting ready to get out whilst his DC patiently queues up outside waiting to come in. I used one a couple of times just to hear the blue Danube, but for me, docking is fun.
IF FD consider all of these issues with an Autopilot (or npc co-pilot) then it could *maybe* work. imo it must never be the most efficient way however
