2016 BMW 740I IS EQUIPMENT WITH AUTOMATIC PARK DISTANCE CONTROL SYSTEM (PDC) THAT AUTOMATICALLY ACTIVATES WHEN THE VEHICLE IS CLOSE TO AN OBSTACLE WHEN DRIVING AT VERY LOW SPEED. THE SYSTEM IS VERY FLAKY IN TERMS OF PERFORMANCE, SOMETIMES IT ACTIVATES WHEN IT IS 2 FT AWAY FROM OBJECT AND MANY TIMES IT ACTIVATES WHEN IT IS ONLY 2 INCHES AWAY.
