When the Ford Lightning is in reverse and the 1-pedal braking system is applied, the brakes don't engage when switching to drive causing the car to roll back an additional 3-5 feet depending on speed. In the situation that caused the fender bender, the Ford lightning was reversing in a street at approx. 5 MPH then the driver released the pedal for the brakes and switched to drive. The car rolled back 5 feet into a parked car during this transition.
