Maybe. I think Tesla used to have a description of Smart Summon on the website where the car can pull out of your garage and transition around a curved driveway to pick you up in front of your house. So Smart Summon may be that instead. At this point, I don't think we really know what Smart Summon will be. Tesla has seemed to drop talking about it. It is no longer on the website as far as I can tell. I suspect that Tesla has decided to just focus on FSD rather than promise specific features. Once, FSD is achieved, it will be a moot point because the car will be able to do those features and more.
If Smart Summon is what I described above, just going around a curved driveaway to pick you up, I believe that feature used to be listed under Enhanced Autopilot. However, what you describe would certainly be part of FSD, yes. In fact, your scenario was seen in reverse in the FSD video where the car drops the driver off and then finds a parking space on its own. So, you would be correct that your scenario would only be possible with FSD. It would not be released before FSD.
It sounds like you are having a hard time grasping the concept of FSD. But real FSD when fully implemented, will actually work really well and no, it won't kill anyone in the parking lot. In fact, FSD would be better than a human. I am a young able bodied person but I was recently pulling out backwards from a parking space at WalMart, very slowly, when a couple banged on my trunk. They were walking past me as I was pulling out and came inches from my trunk. I never saw them despite checking my rear mirrors because they were in my car's blind spot. That cannot happen with a FSD car because it has no blind spots. Every AP2 Tesla actually has ultrasonic sensors able to detect close objects like a pedestrian and stop before hitting them.
No, I doubt think Smart Summon, as you describe it, will be available this year4 or before FSD since it would require FSD to work. But what you describe would be part of FSD. Once FSD is released, the car will be able to do what you describe and it will work really well. I believe that FSD in beta form will probably be released early next year (2019).
