I did make a spice run autopilot AHK script a while ago that just flew you between the two stations, but I think the devs added a few grav wells that make it useless, and I never bothered to update it.
Making these are rather easy as you only need to record your clicks and then play them back. That being said, for me, I see running these while AFK as cheating, and I'm all for kicking/banning AFK bots. So make sure you are around to reply if a server boss PM's you
