NHTSA Complaint #11021375 — 2017 BENTLEY BENTAYGA

BENTLEY DYNAMIC CRUISE CONTROL - DANGEROUS THE CAR HAS DYNAMIC CRUISE CONTROL THAT IS VERY DANGEROUS IN CERTAIN SETTINGS. IT IS POSSIBLE TO SHORTEN THE DISTANCE TO THE NEXT CAR ON A HIGHWAY TO APPROXIMATELY 100 YARDS, AND THE CAR WILL CONTINUE AT THE CRUISE IF THERE IS NO CAR IN FRONT. THEN ON THE HIGHWAY WHEN TRAFFIC IS STOPPED OR SLOW THE CAR WILL DRIVE AT SAY 65 MPH DIRECTLY TOWARD THE STOPPED VEHICLES BECAUSE THE SETTING IS SET AT 100 YARDS. THE RADAR HAS THE ABILITY TO SEE 300-400 YARDS, BUT IN THE SHORTENED SETTING INSTEAD OF LOOKING OUT AT 300-400 YARDS IT DISREGARDS THAT INPUT TAKING ONLY THE 100 YARD INPUT. WHAT THEN HAPPENS IS THE CAR ON REALISING THAT THE STATIONARY OBJECT IS NOW AT 100 YARDS ATTEMPTS TO DO AN EMERGENCY STOP. WHICH IS IMPOSSIBLE. THIS HAPPENED BY ACCIDENT TO ME ON A HIGHWAY, AND I HAVE TO SWERVE ONTO THE HARD SHOULDER TO AVOID A COLLISION. IF THE MANUFACTURER WANTS TO INSTALL INTELLIGENT SYSTEMS THEN IT WOULD BE REALLY HELPFUL IF THEY WERE DESIGNED RIGHT. IT IS ABSOLUTELY POSSIBLE TO TAKE A RADAR INPUT AT 300 YARDS AND 100 YARDS FROM THE SYSTEM AND THEN MANAGE THIS SITUATION SAFELY. THIS IS A BASIC DESIGN FAULT. THEY SHOULD GO TEST A MERCEDES TO SEE HOW TO DESIGN THIS PROPERLY.
