Responding to some of the comments suggesting that Tesla is going to capitalize on this...

I've seen enough of Elon's talks and read enough to know that he is trying to save our species from killing ourselves. Hence the whole reason to inhabit Mars, as he wants to make us a multi-planetary species.

So yeah, most other companies would probably do that but I don't think Tesla will. Tesla even open sourced some/all of their patents so that other electric car companies could enter the market and create more access to electric cars, that lower the carbon foot print of our transportation needs and therefore extend the time we have on earth.
