Is lane keeping really a solved problem? Just last year one of my brand new rented cars tried to kill me a few times when I tried it again, and so far not even the simple lane leaving detection mechanism worked properly in any of the tried cars when it was raining.

What problem is it even solving? Keeping my car straight so I can be less attentive on the road?

I get it in the context of driverless but find it nothing but annoying as a driver.

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.

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.

Adaptive cruise control requires some degree of lane detection. It has to figure out what car it's actually following, not merely what car is in front of it. (The road is turning, the car in front of you can easily not be the car you are actually behind.)
