I WAS DRIVING MY VEHICLE ABOUT 30 MPH, BEFORE I EVEN APPROACHED ANOTHER VEHICLE MY SENSORS BEGAN BEEPING QUICKER AS IF I WERE ABOUT TO HIT ANOTHER CAR. NO VEHICLE NEAR ME CLOSE ENOUGH FOR SENSOR TO BEGIN ALERTING ME. AS I TRIED TO SLOW DOWN , THEY BEGAN BEEPING VERY FAST AND I WAS UNABLE TO STOP, I WENT AROUND A CAR THAT WAS SITTING AT THE STOP SIGN TO AVOID REAR ENDING THEM, AND STILL REAR ENDED A PARKED CAR. POLICE WERE ON THE SCENE AND WITNESSED THE ACCIDENT. MY CAR WAS TOTALED DUE TO A MALFUNCTION
