I'm about to put my deposit down and have been worrying about this problem. My garage is inside the house, under our bedroom. I worry about continual connects/disconnects from putting necessary wear on the mirror motors.
My hope would be that they realize this is not always helpful at home, and enhance the 'walk-up' functionality by adding the ability to disable it when you're specifically at home (but 'on' the rest of the time), most likely by the connection status of a specific wi-fi network. Problem solved.
