My wife and I use summon quite a bit. She uses it every time she pulls in and out of the garage when I'm parked inside as well and I do the same when she's parked inside. We have a Model S and X in the garage. The other day, my mom was visiting and she was parked behind one of the garage doors in the driveway, leaving more than enough room for my car to pull out of the garage. This is how the car looked before I aborted Summon: I don't understand how the parking sensors weren't able to pick up the other car. Usually Summon senses everything around the car. Has anyone else had any similar problems?
