Autopilot still seems like a gimmick to me in its current state. I’ve slowly trolled through side streets and the parking lots of shopping centers on several occasions now for the express purpose of getting the autopilot to trigger and pop up.
Most of the time it doesn’t ever trigger, and even when it does trigger, it seems to me to be WAY less cumbersome and tedious for me to just park the car rather than slowly creep around a parking spot until I see the P, then carefully maneuver the car to where it needs to be to engage AP, then actually perform the right sequence of steps to engage AP (which are not terribly intuitive TBH), then wait for AP to actually park the car, which honestly seems to park at a rate that my 101 year old blind grandmother could probably outpace.
TL;DR - not useful right now IMO. Just park it yourself.
