It is not about communication, it is about function. "You have to constantly pay to keep your car alive. If you leave it alone for a few weeks, it will die". This is the way I read it.
PS. If the battery management system won't allow the car to reach dangerously low level of charge, if it is very unlikely that I will damage my battery by accident - why won't Tesla guarantee it and subsidize battery replacement? Make it a $1K repair, that's enough money to keep people from not plugging their vehicles out of pure carelessness, but don't make it a $40K event that in insurance terms would be a total loss.
