Lane keep keeps your car in the lane so you can stop paying attention just like cruise control keeps you going the same speed so you can stop paying attention… they don’t.

They are just aids that ease fatigue on long trips.

The "fatigue" from long trips is hardly a result of having to keep in a lane.

It's more so the result of being awake, doing effectively nothing, for a long time. Lane Keep assistance is a useless technology for 99% of the population and the 1% who need it, likely shouldn't be driving a car anyways.

The more we "aid" fatigue, the longer drivers will attempt to drive. This cannot be a good outcome. The worst driving occurs when one is practically half asleep.

I’m not referring to mental fatigue, but the physical ergonomic fatigue simply from continually activating muscles in a narrow range of motion even over a couple of hours.

If you’ve ever driven a 1970s truck you’ll know that continually correcting the steering will wear you out after just a couple of hours. Modern rack and pinion steering is a lot more comfortable, and lane keep is a further comfort improvement.
