Is raising the federal gasoline tax the best way to fund highways? The 18.4 cent per gallon tax-the main source of funding for roadways-is raising too little to fix our infrastructure. Gas tax revenue has fallen because fuel-efficient cars have reduced drivers' fuel purchases. Drivers are opposed to raising the gas tax, so would a tax on miles driven be a far better and fairer way to fund roadways?
Would a tax per mile driven be fairer than a tax per gallon of gasoline? Which tax would be more regressive? Explain your answers
