## Narrative
I was driving on Saturday September 3 at 5 pm over the Chain Bridge entering Washington DC. Traffic was heavy and the auto brake went on when I was about 15 feet from the car in front of me. I was using one-pedal driving and when I pushed on the gas slowly we started slowly moving forward. I was traveling around 3 or 4 miles an hour and the car would not slow down when I took my foot over the pedal. One pedal driving apparently stopped working. I then applied the brakes gently and the brakes did not work. I then pushed the brakes hard and still no brakes worked. I tried pumping the brakes and nothing worked. The car gently ran into the car in front of me causing no damage to the car in front and he kept on his way. My front grill was cracked and bumper was slightly damaged. The signal on the dashboard said parking brake engaged which it was not. While the auto safety brake engaged minutes earlier when it was not needed it did not work when the car was drifting uncontrollably into the car in front of me.
