I think it is pretty understandable why Tesla doesn't show enormous profits, everytime you evolve/improve the society it takes time until people realise that will be the future. In my opinion Tesla will be the leading company in some years, just because they have the technology and are very advanced in terms of research and implementation.
When things go right Elon Musk is a genius, when someone starts to lose a few dollars he becomes a mad man, ridiculous , in my opinion. Let the men see the future and help us evolve...
