I've noticed that a lot of people are talking about the auto door lock feature for when you get in the car, I'm looking for a feature that will auto lock the car when you get out of the car. I believe I read somewhere that the new BMW 7-series has a push button key fob similar to the prius but a major difference is that when you are within a few feet of the car, it auto unlocks and when you turn the car off and walk away, the car automatically locks. I am enjoying the fact that all I have to do is pull the handle and the car unlocks but I am wondering if there is anyway that I can have "no interaction" auto lock when I walk away. I get that there is that button on the handle that I can press when I walk away and it locks the car but is it possible to get even more lazy? I'd like to be able to turn the car off, open the door, exit the car, shut the door, walk away, car locks by itself, end of story. possible?
