I think I'm missing something. How's that you'll be driving "for free" ? Someone has to pay for the energy the cars will be spending.The cars need maintenance. The car will be the "fastest, sexyest" for how long?
There is no free lunch. And Mr. Musk is not trying to give humanity free drive for life... he's just trying to make money. He is just trying to make his stuff popular so he can sell more of it and make more money. It's just business.
