After looking into it a bit more, it seems useful in some circumstances as you describe, but hardly "summon it like a valet" when it can only move a few meters.
From your description, I was thinking more of something like waiting at the entrance to a public carpark and the car comes to you.
This is called smart summon. It can turn, reverse. It’s not perfect and if you know it’s limitations you can manipulate it so that it works 99.999% of the time
No, I have smart summon. It can actually go from the parking spot, turn toward me and pull out up until where I am standing. This is real look it up on YouTube or I’ll send you a link myself
