How's it short term?
The credits aren't going to be massively going to be cut, fossil fuel costs are only going to rise. Push for clean fuel is only going to rise, as seen in the recent signing of COP21.
As I said it takes time for things to happen, big car companies can't just wait then come out swinging. They have to have a lot if things in place first, that is why their heads are in the sand. The only thing that makes it slightly easier for them, is Tesla has released the patents and will allow deals to be made to use their supercharge infrastructure.
I don't see why you think part of the industry is right and the other part is wrong.
Everything points towards electric, that is what invade it on. Just have to look at EU and other countries plans, looks at things like COP21. Look at how price if batteries have fallen, whilst capacity has steadily increased.
Or just look at what you were saying two years ago, that Tesla sucked and no one would like it, compared to know where a large portion would actuary like a Tesla if it was affordable.
Big companies can and do make massive mistakes by burying their heads, look at NOKIA under estimating smart phones.
