autopilot

A mechanical, electrical, or hydraulic system used to guide a vehicle without assistance from a human being.

I set the autopilot to due south, so I could get some rest.

A state of mind where one no longer thinks about doing one's actions, but acts mechanically.

I've been doing this 12 hours non-stop, and am so hungry and tired that I've stopped thinking: I'm now on autopilot.

But while the wackiness gets exasperating fast (a running joke about Hazel’s father, played by Ray Romano on autopilot, having a sex doll for a wife is even unfunnier than it sounds), Milioti works overtime to keep us invested.

To pilot itself; to drive or travel automatically.
