The gas/diesel industry produces about $40B/year in taxes, but also, they consume about this much in the form of subsidies. So why not eliminate these pricing distortions for less bureaucratic inefficiencies and also have more accurate pricing signals?

I was surprised that the gas taxes generated and consumed by the gas/diesel industries are about the same. So why do we need them anyways since they both behave antagonistly? The tax makes diesel/gas more expensive, but the subsidy makes it cheaper. So we should eliminate them to reduce the bureaucratic inefficiency and to allow the industry to set prices and not a centrally-planned command-style economic plan that the nation has devised.
