Wait! I just had an epiphany! It just dawned on me why Elon never delivered an SDK for Tesla apps! If there was a Tesla app ecosystem, a "fart app" or "sketch pad" would not get any media attention, like a "fart app" or a "sketch pad" for an iPhone wouldn't. So, we'll never get an SDK which would allow people to write apps for Tesla (a vision which Elon sold us on 6 years ago) simply because it would limit Elon's ability to grab media attention with the likes of a "fart app".
Next up,
"I am rich" app, *cough*, I mean easter-egg.
