After I turned on the car, unbeknownst to me, the Ford Bronco stayed revved up and it did not slow down. I then switched from park to reverse and the Bronco went so fast (>4000rpm) that I ended up hitting the tree so hard that the tree was uprooted. The car was not driveable and it had to be towed. This is under progressive insurance claim: 22-3913700. The insurance company would not check the "inside" of the car (etc...transmission, electrical, etc...) as they say this is prior to the accident. I have called the Ford dealership for assistance several times to report this and for them to take a look at the inside of the car, but they have not returned my messages.
