2017 FREIGHTLINER CASCADIA Vehicle Speed Control Problems

THIS COMPLAINT PERTAINS TO ADAPTIVE CRUISE CONTROL (ACC), FORWARD CRASH AVOIDANCE (FCA) AND LANE DEPARTURE WARNING SYSTEMS (LDWS). I HAVE BEEN DRIVING THIS SPECIFIC VEHICLE BUT IT WILL PERTAIN TO ALL VEHICLES WITH THESE SYSTEMS. THE ACC AND FCAS BECAUSE OF ITS STRAIGHT LINE OF SIGHT IS MISINTERPRETING THE DATA ON APPROACH TO BRIDGES, OVERPASSES AND OVERHEAD SIGNS AND WILL INITIATE A HARD BRAKING EVENT ON THE INTERSTATE WHEN NO BRAKING IS REQUIRED CAUSING THE POTENTIAL TO LOSE CONTROL AND FOR A FOLLOWING VEHICLE TO CRASH. THIS PROBLEM WOULD BE INTENSIFIED ON WET, ICY AND SNOW COVERED ROADS. I HAVE ALSO EXPERIENCED A HARD BRAKING EVENT ON INTERSTATES ON APPROACH TO A CURVE IN THE ROAD WHERE VEHICLES AHEAD WILL ALREADY BE IN THE CURVE IN ANOTHER LANE AND THE DATA IS MISINTERPRETED AS A CRASH AND BRAKES HARD BECAUSE THE OTHER VEHICLES ARE DIRECTLY IN THE LINE OF SIGHT....
