I remember Obama saying he thought gas should be $6-$7 a gallon soon after he took office. Inflation adjusted, that's probably around $10 or more today. And, I remember thinking you have no clue what will happen to the economy. And, when it got expensive back then, around $4, my wife and I had to make serious decisions on what was important in daily life.
If everyone gets an electric car I can see the power grid failing miserably to sustain them. So...I guess it's expected by them for us to deal with constant rolling blackouts.
