Elon Musk sent this pair of tweets this morning. The Summon/Unsummon commands are supposed to work today on your iPhone or Tesla key.

Tap your phone or key and your car will open the garage door, exit, close the door and come to you. Will do same in reverse for unsummon.

In ~2 years, summon should work anywhere connected by land & not blocked by borders, eg you’re in LA and the car is in NY
Now we know why Tesla is developing the robot arm that plugs their fast charger into your Tesla charge port 🙂 So you can park your car in NY and tell it to pick you up in LA. It will just need to navigate to the string of cross country Fast Charging Stations. Story and robot arm video at Wired.
