I have some serious concerns about Tesla, and here's another.  I hope Elon Musk isn't going to preach about morality in the marketplace, because this little "feature" of charging thousands of dollars for something that doesn't cost the company much of anything, is an immoral way to run a company.  If I were one of these owners, once I thanked Tesla for getting me out of a jam, I'd be outraged at the scam they're perpetrating when selling the cars.
