Following my wife home, she parks on the driveway & opens the garage using her remote in her ICE, I arrive ~30 seconds later driving the S, seeing the garage already up I don't stop on the driveway & proceeds to park into the garage when the door automatically starts coming down 2 feet before entering, the sensors would have stopped the door (I hope) but GPS & the car knowing my direction of travel should have never sent the close signal.
I think you're expecting this system to be a lot smarter than it is. It's an on/off stateless affair, which is why they include the cancel button. I had the same concern once when my wife had the car and I left the garage door open. She noticed it coming down before pulling in, thankfully. I think it'll just take a little adaptation. I don't see them making the algorithm a whole lot smarter, though.
