As I posted on the main thread by accident I'll cross-post here as it's relevant.
The car now has Autopark / Disable continuous press as an option. This means the car will keep driving with a single click with no one in the car. Interesting times ahead.
Require Continuous Press: By default, Summon requires that you press and hold a button on the mobile app or the key fob accessory to move Model 3 during the parking process. When Require Continuous Press is set to NO, you can press and release the button—you don't need to hold it down to keep the vehicle moving. Also, Require Continuous Press must be set to NO if you want to operate Summon using the key fob accessory instead of the mobile app (see Operating Summon with the Key on page 94), or if you want to start a parking sequence from inside the vehicle (see Starting Summon Before Exiting the Vehicle on page 95).
Basically you can enable auto parking the car before you exit, then exit and it will park itself. Or you can summon with a single click and not have to hold down the key fob / app button.
