It is a Docking Computer, it isn't a fully fledged auto pilot! I've never crashed using the Docking Computer. I always stop at aprox 6.5kms from the space station, then request docking permission then when accepted, the docking computer does the rest...perfectly every time.
If I am going too fast the docking computer will not work efficiently or at all, as the speed overrides it. As stated its not an auto pilot its only an electronic docking mechanism. Slow down and stop, request docking permission and it will work every time or your money back.
I do maybe 40 to 50 docks per session of play as a trader...so yes I use the DC...its a Godsend or I'd go mental doing all that lining up and slowing thrusters back, up, down, left, right, left, right, down, left, right, back, forwards a bit, down, up, left a little more, right, down slower, up a bit, left a bit, right a bit, forward a bit more, forward a little bit more, down just a tad, down just a tad more, down just a tad more, up a tad...too much....back down a tad...too fast....up a little bit more, down slow, down slow line up, line up, left, right, left, right....nearly...nearly....okaaaaay....got it...waheeey! 30 to 40 times a session, yeah right!
You are my hero - I 100% agree with you.
