Interesting.
> A REST-like API on :8080 which returned a history of “tasks”
I am curious to know what kind of historical tasks- since it's a media control unit; does it show what kind of media was being played in the last trip? does it reveal any other info about the driver?? There might be a privacy angle here that you could exploit and share it with Tesla.
They hit Odin. Odin is the diagnostic tool of Tesla. The tasks they've seen are like "TEST_BRAKE_X_STIFFNESS-TEST-PRESSURE-BURNISHED" and are used to test different components of the car. They're also used for example to reset FSD strikes.
In Tesla terms, the infotainment does much more than just playing music - it has full access to the rest of the car.
