This is very interesting...
Did you know that there is a push from GM to not allow anyone to tune their cars? If this gets passed in courts, and you take your car for service at a dealer, and they find out that you have touched the tune, you get a HEFTY fine!!
Don't believe me? Look for John Deere. They have been taking farmers to court over the "tunes" they're putting in their farm equipment, and it's setting a precedence that GM can follow through with as well as other OEs. If it passes, it would treat your vehicle software like it does any other software...that you decompile and modify it. It will also treat your vehicle, the way John Deere has won in court, that you merely "lease" the car, whether purchased or not, for it's usable life and aren't allowed to modify it in any way.... John Deere technically now still owns all farm equipment "sold" to people now.... Do I agree with it? Yes...it's software. If we want to have laws governing computer software that was painstakingly developed, why shouldn't it apply to vehicle software?
I have been following the John Deere situation and unless I missed this getting overturned I think you are behind the times.
In October 2018 the Library of Congress adopted an exemption to the DMCA specifically to make it legal to circumvent access controls for "non-infringing" purposes such as repair.
Further, Minnesota seems to be about to pass a Right-to-Repair law of its own.
I don't think that either of these compels manufacturers to provide the tools or information needed to do it, but they do make it legal.
