Presuming it's true. I used to build electric cars. They're hella simpler than gas cars. There's a pretty simple way to fix this: you put a floor on your battery discharge and if you get below that limit, you pop the contactor and throw all your auxiliary systems into hibernate mode. You get on your GSM network and you have the car send you a text saying "your battery is fucked, yo, hurry up and fix it." Finally, you set the thing to give off an audible alarm. All this stuff is easy to do, particularly when you have an operating system. Here's the thing: your iphone won't do this. Your Leaf won't do this. If Teslas really are doing this, it's a big fucking problem. The thing is nothing more than a Lotus Elise with an alternate drivetrain, and electric drivetrains are stupid simple. If there's anything to this, it's wholly inexcusable.
