I legitimately used smart summon this morning. I was parked in the end space in front of my kids' school and came out of the building after a meeting. As I approached the vestibule I could see the car through the windows and could also see that the area between the single parking row and the building was completely empty of vehicles or pedestrians so I summoned the car, setting the target as the front of the building, right in front of the doors.
By the time I exited the building, crossed the sidewalk, and entered the parking lot in front of the building, the car reached its target. It was very cool not needing to walk the entire length of the parking row to get to my car.
That's cool that it worked. But the thought of people testing this function in my school's parking lot terrified me. Perhaps we should try it somewhere else first.
