Just kidding—that would of course be ridiculous. No, the wonder of prices will do the job just fine, thank you very much:
The latest figures from the Department of Transportation show that in March, when fuel was a far more modest $3.22 a gallon, Americans drove 11 billion miles (17.7 billion km) fewer in comparison with a year earlier. The decrease compared with the previous year, of 4.3%, is the first since 1979, and the sharpest since 1942.
As I enter the final stages of finding a suitable abode in the US, the prospect of $4.00/gallon gas is one I view ambivalently. In the short-term, I will remain earning a low income, and since I will be living in a place where substitutes to driving are not feasible, I do not relish the extra expense (especially since it will comprise a much larger part of my budget than the typical 5 percent). However, I see relatively high gas prices as the best way of precluding further illiterate, incoherent and counterproductive energy policies enacted in the name of energy independence and/or combating climate change.
