Cheap gas is gas that gets used a lot. Gas should be far more expensive and when it is then people will see that other alternatives will be created. Electric cars may be expensive now but everything is expensive in the beginning. A computer that once cost thousands now is carried in your pocket and is called a cell phone. Electric cars with flash recharge, solar roof parking lots that charge while you are at work etc. Home solar roofs charge at home, maybe even solar charge parking spaces using a charge meter (by induction) like where a parking meter use to be. Maybe even solar charge roads that charge your car as you drive over them.
But not while gas is cheap. Then there is not a pressing need to save the planet and stop global warming. While gas is cheap it is used a lot and then we all await that sudden climate catastrophe (sudden being a relative term) to make us change our minds about using fossil fuels so much.
We await that killer storm as big as Sandy but with high gale force winds of 90 to 150 miles per hour instead of Sandy's relatively benign if wet 60 to 80 miles per. We await that ten foot sea level rise that convinces a helluva lot of people that they shouldn't buy any beachfront property ever again. That drought that never ended and wrecked a nation's agricultural breadbasket and sent it up north beyond the border.
That is what cheap gas does... oh and yeah it doesn't fix potholes but maybe there are better reasons to raise the price of gas.
