The Tesla Model Pi is either very cool technology or an elaborate joke. I'm pretty sure it's a hoax.
There has been no announcements of any kind from Tesla and if you think about it - the SpaceX Starlink receiver for broadband service is about the size of a pizza box. No way that footprint has been shrunk to the size of an iPhone.
There have been many cool features attributed to the Model Pi - hopefully some day they'll become a reality (instead of an elaborate prank).
