They corrected to 2-wheel mode, checked to confirm no damage, and wrote it off as driver error/lack of general knowledge.

Lane keeping will kamikaze the vehicle on to exit ramps or exit only lanes when engaged at a highway speed. This seems most common when the truncated lane markers, usually used on exit-only lanes, and not the full length lane markers (the center line markings). Example: Vehicle is traveling at a static heading, freeway speed, two lane limited access freeway, driver in control, all lane keeping and adaptive features engaged. When an exit lane approaches on right, vehicle abruptly deviates to the exit lane with zero driver intent or inputs. Once vehicle system realizes the error, system alerts, notifies of a lane departure, and disables the lane keeping. Particularly problematic is that vehicle actively fights driver inputs to restore the intended course as it appears to believe the driver is in error. This is not a one-off occurrence. It is very consistent. To the point when I can anticipate, disable the system or counter steer to keep the vehicle course straight. It seems the vehicle cannot properly identify the shortened / truncated pavement markings correctly, leading to this undesirable course adjustment.
