auto locking when walking away

with the push button start system, when you turn the car off, get out and walk away the car should automatically lock all the doors.

Keep the fob in your pocket and the doors will automatically unlock again when you get close.

What if you are unloading groceries, kids, luggage, or whatever else and its raining?  Just because I shut the door and walk away doesn't mean I am done getting in the car.
