I parked my 2011 cadillac model srx in the garage and walked away from it and closed my garage door. one hour later i opened the garage door and the vehicle rolled down my driveway and over a curb and hit a tree. the car was in drive. on a normal automobile there the driver needs to put the car in park in order to remove the key. this feature is pretty universal in every car i have operated. this feature is not incorporated in my new cadillac. it uses an electronic key that does that can remain in your pocket. there was no indication that i was leaving the car in drive vice park. if a child had been in my driveway this accident could have been much worse. the damages to my car were $2132.89 and the loss on 10 days use of the car. *tr
