Disregarding legal issues I pondered this scenario. Place Phantom in middle of open area at home. Install battery and set home point by starting motors and then stopping. Without removing battery drive down the road a couple of miles. Launch from that location with enough altitude to clear any obstacles on rout to home location. Turn off remote and watch phantom fly cross country and land in your yard. I figure I would be good for about 3 miles with my extended battery since I have flown as far away as 1.25 miles and back with plenty battery left. This is just a thought experiment, I would never do it!
