I'm fully supportive of someone going to court and finding out what happens when they do this. It is far more valuable than wild speculation. Copyright law is bad and should be changed, but that is unlikely a winning defense in the course of a civil suit (or criminally, if prosecuted for DMCA violations, such as circumvention of digital mechanisms for access control per 17 U.S.C. § 1201(a)(1)) [1] [2]. I am fairly confident (not an attorney, not your attorney) this applies to access to Tesla's FSD digital work.

(circumvent a technological measure (3) As used in this subsection— (A) to “circumvent a technological measure” means to descramble a scrambled work, to decrypt an encrypted work, or otherwise to avoid, bypass, remove, deactivate, or impair a technological measure, without the authority of the copyright owner; and (B) a technological measure “effectively controls access to a work” if the measure, in the ordinary course of its operation, requires the application of information, or a process or a treatment, with the authority of the copyright owner, to gain access to the work.)
