The car suddenly picked up the speed in the parking lot, went over the car stopper, curb and hit the Tree. The airbags never got activated, OR the sensors were nonfunctional. I received a call in less than 1 minute from Tesla Roadside if I was safe. Paramedics took me to the ER by 911. I had some injuries because of a malfunction of airbags, brakes, and warning systems. The car is towed to the nearby Tesla-approved repair place. I am somewhat concerned about the cause, and I believe Tesla knew what had malfunctioned in their car. I have been a safe driver without traffic tickets and accidents ever in the last 45 years.
