The point at which Tesla will become not a pie-in-the-sky wet dream is when the price point matches a run-of-the-mill Honda.
Right now, having a Tesla is like having a Maserati.
I know zero people who have one, my wife (a structural integrationist) _works_ on people who have them, so I am like two social tiers away from thinking of affording one, which, for me, is like dreaming of that Kawasaki Ninja I had postered on my wall as a ten year old boy.
He, and his team, need to dramatically scale down costs somehow. I read something cool today about Chinese charging stations that swap batteies instead of sitting and waiting to recharge. I wonder if something like that with an attendant would work to extend the battery "life" ad infinitum for grids in other nations.
Seems like his head is on straight though. He took profits and looked up. He said, yeah, I could drive down prices on my car by saturating more, but I'll build rockets that don't waste as much on reentry costs instead. That's smart innovation, that's passing the baton in the 400m instead of sprinting 10m and saying "I win!".
I do think there is stigma (even in my own mind, and I really am a fan of Elon) surrounding borrowing money over and over, but the reality is: almost EVERYONE does this. If you aren't Dow, or Ford, or some huge ass fucking company that has a war chest the size of Dubai, you aren't going to weather the stormy market conditions we are facing as a result of globalization (see Brexit et al for moreon that topic of discussion).
Businesses need floating because they don't exist in a vacuum, they exist because they aren't welcomed by their competitors, in fact, they are actively "sabotaged" by those that stand to lose market share, and that, my friends, is a HUGE problems with mercantilism. Unless we decide to get along, it's not going to get better, and corporate espionage has not lessened in my lifetime, not by a moonshot.
So, yeah, play nice and he and those like him will stop having to borrow money, and maybe he will throw us a bone and make a car that doesn't cost as much as my entire post-secondary education (including grad school).
Peace y'all.
