This is the excellent statement but coupled with the threat of being kicked off the warranty (which means no repairs whatsoever since no independent shops) and being assaulted by lawyers with charges of industrial espionage if you veer a little to the left or to the right does not exactly make it a model citizen. Hacking culture is all about doing things manufacturer did not think of. Yes, sometimes that can lead to screw-ups, including ones worthy of voiding the warranty, but so far it seems like Tesla is in full "besieged castle" mode, and even docs you mention are unofficial - which means a) they could change anytime and b) you could be charged with espionage for using it anyway.
