According to Thomas Friedman's recent op-ed in the NYT, given that oil prices are way down compared to last year, it's time for a gas tax, but we don't have the guts. We don't have the guts to make hard decisions like France and Denmark, which have both dramatically reduced their dependency on petroleum. Further, a gas tax would also generate much-needed revenue.

Such a tax would make our economy healthier by reducing the deficit, by stimulating the renewable energy industry, by strengthening the dollar through shrinking oil imports and by helping to shift the burden of health care away from business to government so our companies can compete better globally. Such a tax would make our population healthier by expanding health care and reducing emissions. Such a tax would make our national-security healthier by shrinking our dependence on oil from countries that have drawn a bull’s-eye on our backs and by increasing our leverage over petro-dictators, like those in Iran, Russia and Venezuela, through shrinking their oil incomes.
