The lane keeping assist and/or lane braking assist will violently move the vehicle unassisted by driver onto access roads the driver expects the vehicle to maintain its position of the highway and not to violently turn onto access roads.. it is particularly unsafe on 75 and 85 mph speed limit highways. requires driver to violently jerk wheeler back to the highway being traveled upon. calls directly to mercedes indicate no interest in the problem and software involved and local dealers either will not set up appointments for inspection or/and indicate they cannot correct the software or sensitivity of detectors on right side of care. the only way to avoid this is on a 4 lane high by staying in the center passing lane a lane away from exits.
