I think growing up in a snowy climate where super precise throttle control is critical to not ending up in ditches plays a huge role in why I zone out when using cruise control. The fine motor skill of throttle control occupies the back of my mind while my conscious thoughts rotate through the mirrors, track other vehicles and watch for obstacles. I can maintain a speed within a couple km/hr for a very long time without needing to glance at the speedo at all.

The moment the back of my mind doesn't have to handle precise throttle control I find my mind wandering and my spacial awareness is shot. I guess maintaining speed is the fidget spinner that keeps me focused on the task of driving.
