Prediction: In the next few years governments will start to require cars to be electric, and the car companies will support it.

Think about it. Everyone will be pissed, but ultimately people won't do shit and they'll just buy another car. So if they say something like by 2022 all cars on the road must be electric, there will be a massive surge in sales for the car companies. This will also cut the competition from the smaller companies that don't have electric models.

Tesla is the fastest growing car company, but Toyota and Chevrolet both sell more electric cars then Tesla. They're probably waiting for that moment when their production numbers will meet the surge in demand, and Tesla is likely a thorn in the side of the big boys.

Just some thoughts.
