There are some suggestions that it has already gone into structural decline, although I disagree with most of them as I think petrol products are still the most cost effective way to take a newly industrializing economy to the next level.

It occurred to me driving home today that if Elon screws up and suddenly all of the Supercharger stations go away at once, its going to really put a pinch on owning an electric car. And yet, if he can get to the point where others are building super charger stations because they can make some money at it, then the market flips to electric cars by default.
