I prefer Lane Keeping Assist to Lane Centering. The Ford system is the only LKA I have experience with. It has me drive but warns and intervenes when I get close to the line without signalling. Before it nudges the steering it shakes the wheel and it feels just like rolling over a rumble strip. In cases where I do legitimately get distracted and start to drift that rumble snaps me back to driving before things go awry. False positives almost completely come from changing lanes or exiting the highway without signaling. The rumble strip feeling and then the steering input isn't strong enough to prevent the lane change but does give me that reminded to signal next time. The nudge is strong enough to keep the car in lane but no one in their right mind would let the car go down the road bouncing off the lines like this. To me there's no question that I'm driving. I stay engaged and alert without every having to be monitored and nagged. It helps me when I slip but doesn't make me complacent. With a Lane Centering systems the car is doing all of the subtle corrections. I don't feel like I'm driving and I totally drift off. I feel much more checked out and thinking about it after the fact I feel much less safe over time.

I totally want to study this and see if it's just me and then publish. Oh well, if I ever jump to academia.

Tesla's initial Autopilot run was literally LKA running on a loop. Mobileye had put that exact sensor suite in dozens of production vehicles but left it to LKA duties due to the inherent danger of expecting the user to take over at any moment. To that end, the system actually provided more input when it detects wrong input than when it detected no input. For example, feel a strong nudge when you try and change lanes without signaling before you leave the lane, but with no input at all the car would be riding the line before correcting, essentially preventing hands free usage It focused on correcting behavior without causing sudden hard to correct errors... like driving into a concrete barrier when your hands aren't ready to provide counter-input

The Honda system is almost exactly how you would describe, and it's pretty great. Sometimes it's a tiny bit too aggressive for me as I like to sit towards the very outside of the lane (if I am in furthest left or right lane) to keep max distance between myself and other cars. More distance buys you more precious reaction time. Otherwise, a fantastic system.

  I have the same experience with Honda Sensing. The honda drives much closer to the double yellow then I like. Apparently it is possible to recalibrate the system but from this video it looks like a rather involved process. https://www.youtube.com/watch?v=RsnHOgFnJLw https://www.youtube.com/watch?v=RsnHOgFnJLw

I wish the Honda LKA were tunable, it's much too noticeable when it nudges you back into the lane. I typically disable it on long car drives because in California even long car drives often have a lot of other cars that I keep my distance from, and I have a kid who gets motion sick easily. If I keep the LKA on, on a typical drive it results in a bunch of jerky movements that trigger his motion sickness. If it were paired with driver monitoring it could know that my eyes are indeed on the road and nudge less or not at all.

Teslas work exactly like this without Autopilot. It's one of the assistance features, just like warning if someone stops in front of you and you don't seem to be reacting. These features also get better as Autopilot gets improved with less of the nasty edge cases. So even if you don't trust Autopilot, Tesla's improvement of the system over time is still useful in improving those other assistance features.

Hyundai/Genesis have limited hands-off lane keep. I did a road trip across SD with minimal intervention. No need to use the pedals, and only the system-required steering wheel nudges.
