I found limited uses for it. I do back out the car from the garage to the driveway, so that I can enter the car without risk of slamming the door into anything. I'm not able to self park in my garage since the garage has a "lip" on the ground, and I guess the lip is tall enough to make the car think it's an obstacle... What are some really good uses of summon besides just showing off to your friends of course.
