Are you referring to the motorcycle lane?

I get as far away as I can from actually meeting people: The Clarity is much more social than me.

I may be confused by the abbreviations, but my Clarity kept shaking the steering wheel and telling me to drive better, until I turned it off with the buttons by my left knee... Do some of those buttons relate to this discussion?

Sort of. The button by your knee is the Road Departure Mitigation (RDM) button. Lane Keeping Assist (LKAS) is enabled by the "main" button on the steering wheel (which also enables Adaptive Cruise Control (ACC)). RDM is designed to keep you from driving off the road. LKAS is designed to assist you with staying in the middle of the lane. They work in concert if both are active. LKAS feels a bit more intrusive than RDM, providing more frequent and stronger steering inputs. It may be preferable for you to adjust RDM sensitivity in the vehicle settings (accessed via the touch screen) rather than completely disabling it.

As far as I know, RDM is just a warning system, that jiggles your steering wheel but it does Not actually steer you back into your lane. RDM works at any speed.

LKAS on the other hand will try it's best to keep you in the middle of the lane and actually turn the car to follow the curve of the road. LKAS (with ACC on) doesn't actually activate until speed of ~47 MPH and above.

According to p 396, it applies steering torque as well as rapid vibrations. It may also apply the brakes if it determines that it’s steering input is insufficient to keep the car in the roadway. Braking is applied only when the lane markings are solid continuous lines and cancels if you turn the steering wheel to avoid crossing over the detected lines.
