Or we could try the radical concept of eliminating stupid spending that government shouldn't be doing so that our tax dollars go for something useful, such as roads.
Not a bad idea, except that stupid spending fuels a large part of the economy. Cut it and the economy collapses before things can (hopefully) adjust to something else. Road building alone won't make up for the loss of government provided money in other areas of the economy,; only so many roads are needed and anything beyond that gets back into the area of stupid spending. Fuel tax seems to be one of the only (maybe the only) tax that actually end up being used for what it is supposed to be used for.
