“I purchased a brand new 2011 mercedes benz GL450 4matic last night. The car has a keyless go system. When I was pulling into my driveway with my kids in the car this afternoon I accidentally turned the car off without putting the car in park and began to exit the vehicle. I noticed the car started to roll back down my driveway. The car never went into park when I turned it off. Rather it went into neutral. I have never driven a car that didn't go into a park mode when the engine was terminated. Thank goodness a child wasn't playing in my driveway or my dog was there. …”
