I was driving the car on supervised self drive and going home around 9 pm. When I reached my house I tapped the break to disengage the FSD and take over so that I can pull into our driveway. After coming to a stop the car all of a sudden just took off on its own at almost 60 mph on a residential street. I was repeatedly pressing on the brake to try to control the car. But it seemed like the car had a mind of its own and was not responding to me at all. approximately 8 seconds (based on Tesla dashcam recordings) later after travelling a distance of approximately 700 feet the car hit 2 parked cars on the street, which eventually activated the brake and brought the car to a stop at the front yard of a house across the street from where the parked cars were hit.
