You seem to be striking quite wide of my mark.
First, the point that I was trying to make is that the type of car – in and by itself - does not necessarily change the amount of gas being consumed. People could buy a big car but make fewer trips, resulting in lower gas consumption. With more efficient cars, longer commutes are possible for the same amount of gas, so less efficient ex burbs flourish.
We should have a tax on fossil fuels which would make green energy cheaper...
How do you figure? How does higher gas make my solar panels more efficient? Maybe relativity cheaper, but going green will cost money. Personally, I think it is worth the cost but let's not pretend that it is going to be free.
Isn't strange that car retailers didn't demand to sell Teslas themselves, but instead aim at preventing Teslas from being sold? What is at play here?
No, nothing strange and it has nothing to do with being green. A large corporation is muscling its way into a business dominated by local family business. The family business don't like competition so they are fighting back. It is like asking what Apple has against Microsoft and why doesn't Apple well Window computers in their stores? (Personally, I am rooting for Tesla)
