i like the summons feature as i have a car in a very very tight spot, and love the use. its difficult to open the doors in the tight spot. however, when i try to summon car from the rear and side, its difficult to get done. takes me a few tries to get the key fob to work right. i usually rely on seeing the headlights, but cant when im in the back. any easy way to summon it to reverse when i near the back of the car?
