I left my car in park and running on the driveway. I went out to turn it off, opened the drivers side door and went to push the button to turn it off. The car started rolling down the driveway I tried to stop it as it rolled into the street. I hurt my foot/leg and the car eventually stopped when it went up on a curb and hit my neighbors landscape wall The contact has mentioned the extent to which they were injured that required the use of crutches and a walking boot. The vehicle is still in their possession.
