Even Consumer Reports noted the losses, and it was a long time ago and it hasn’t been fixed:

CR: “When it’s left unplugged, we noted a parasitic loss of energy that amounts to 12 to 15 miles of range per day. That could be a concern if, say, the car is parked at an airport for an extended period. Tesla has promised a fix for that.”

We are so enamored with Tesla that most in the media has looked the other way. And that observation of CR was forgotten. And now David Nolan has documented it well, and the fix isn’t there to date.

The significant vampiric loss flies clear in the face of the efficient and elegant designs that Tesla are striving for and advertising.

Also according to their engineers the problem is not related to the batteries leaking electrons, so yes, Elon did not invent the batteries and the battery has nothing to do with the problem, unless they misdiagnosed this. And they claimed they can reduce the losses to just 1% of battery capacity when the firmware update is done in 2-6 months from now. That would be a total of up to more than a year after the problem was first detected! And I thought they are quick to fix this, as quick as software or firmware upgrade. But we shall see if this gets ever done in 2-6 months. I am keeping the pressure.

We need to keep these companies in top shape so that they will succeed. I am all for their success. Just do not let them overhype while overpriced.

I’m going to assume that he’s moving as fast as he thinks best. Elon does not invent batteries nor control their price. Releasing a more affordable long range EV can’t be done until batteries permit.
