Has Tesla ever made specific reference to what defines the end of "the life of the car"? Or put another way: has Tesla stated the circumstances under which it will revoke free supercharging? This might sound like a pedantic question, but here are some examples where I can imagine it arising: 1. Car is involved in an accident. Many electronics are replaced so many serial numbers no longer match up with the original. But the "car" is effectively the same -- same battery, same motors, same frame. 2. DIY project: someone transplants the Tesla drivetrain or power system into another frame. Now you have a different VIN but the same original hardware. (I know there has been at least one example of this in the Fisker Karma, which has successfully supercharged -- but I don't know if Tesla weighed in on this or what the fine print says). Does either, neither, or both of these scenarios result in a loss of free supercharging? I see two ways to approach this question: (1) What technical scenarios would Tesla recognize as a different car?; and (2) What would Tesla corporate consider a different car? I am mostly curious about (2), but interested in discussion of either.
