To have gas price signs show how much tax is being collected on each gallon of gas.

I just want to have transparency when it comes to the tax that is applied to gas. It should be displayed with the Gas prices how much tax per gallon is being applied. We know how much sales taxes are, we know what income tax bracket we belong to, we know how much property tax we have to pay, we even know how many calories are in fast food meals, but we do not know how much we are being taxed for each gallon of gas that we buy. We purpose that that a pre and post gas price be posted on signs and pumps, or just the taxed amount posted on signs and pumps, or at least printed on the receipt.
