This has been discussed by 
staff, but doesn’t come up a lot. It’s fair enough that you wouldn’t know what to search for to find the topic. I’ve linked one of the references below. If you search the forum for Autopilot - and ignore anything to do with Tesla - you should find a few more mentions.
I’ve no idea when it’s coming, but I believe it is planned. Autopilot sounds, to me, very similar to T212’s Pies feature.
