Nah that will be taken care of by the little black boxes with a GPS sensor and wireless sending unit that Bush will mandate be on all automobiles in '07. They will track how many miles you drive, then send that information to the IRS, who will then send you a bill.
You could line your vehicle with aluminum foil, but then the Men In Black will come and take you away to one of Bush's secret torture prisons where you will be taught the finer points of mass oil consumption and why you MUST pay for it.
Oh, and Bush will also be making $.25 of pure profit all for himself per gallon of gas sold AND per mile drive.
But seriously, it's just like smoking. There is no way that Congress could survive the massive tax hit if people actually stopped smoking. They wouldn't have anywhere near enough money to throw away on useless horseshit.
