I don't believe I am. Verified software on your vehicle is no different than other safety features required by law. Break the law, you lose your right to drive, or you go to jail (depending on the severity of the violation).

I am _not_ arguing you shouldn't be allowed to tinker with your vehicle. You're just not entitled to the source code that runs it (unless you buy a car from a manufacturer that agrees to that as part of the sale agreement), nor are you allowed to make modifications and take it out on a public road if you could cause harm to others.
