Dear NTSB Team, I am writing to formally report a serious safety incident involving my 2019 BMW 530E, which occurred last night on [XXX] in Danville, CA. My vehicle was parked in my friendâs private driveway, with the parking brake engaged and the gear selector set to Park. I was chatting with my friend who was in the passenger seat . My feet were on the floorboard, my seat belt was on and the engine was idling to provide heat as it was a cold night. Suddenly, about 10 minutes into our conversation, my car accelerated forward with speed, hit my friendâs garage door and then reversed with the same speed and stopped in the middle of the street. This happened within the span of a few seconds at most. I think that I applied the brakes while the car was reversing with speed and I remember the car not slowing down but then it coming to an abrupt stop in the middle of the street. There were deep skid marks on the driveway, my friendâs garage door was damaged, my friendâs Tesla X was damaged with impact to the rear bumper, this parked Tesla had moved forward and crashed in the wall of the garage and a garage cabinet door dislodged and fell on the hood of this Tesla. My friends parked Toyota Prius also had bumper damage. The garage drywall sustained cracks as well. The force from these unexpected accelerations and impact has left me and my friend with aches and pains in the back, shoulder, knees, hands, head and neck; thankfully, we did not suffer more severe injuries. I
