That's totally fair. I think it depends on the person and what they have going on that day. I remember, or rather do not remember, getting to work in my last car because my brain did the driving task while I was lost in thought. When I'm using lane keep, I feel like I'm hyper aware of what the cars around me are doing and what road changes are coming that I need to manually adjust for. I could see that getting very boring late at night or on empty highways though. Everyone is different and that's just another element of the equation that the car doesn't account for.
