You know those things take virtually no power, right? These are 50KwH+ batteries and you're worried about I don't know how many fractions of a millijoule.
Do you have any hard data on this, or are you just "jumping to conclusions"?
I'd love to see a comparison on how long the battery can sit if it is physically disconnected from anything drawing current, and how long it can last when plugged into Tesla's phone home system.
