I think it would be great if states were forced (otherwise CA would not do it) to Print a detail of how much of the money you paid at the pump went to Fuel, then each separate tax % and total spent as line items on your gas receipt. That way People will see it and get mad. It should also have a web url where you can go and input your zip code and see all the related taxes with contact info.
Right now in CA they put it on a small sticker on the side of the pump or something.
This offers full transparency for how much the fuel actually cost per gallon minus all the taxes.
