Gasoline markets today are the result of almost a hundred years of conflicting regulatory policies, which have left them dangerously fragmented[;1] the unintended consequences of regulation that have pushed the United States into a series of loosely connected regional markets rather than a broad, deep national market.

It also produces higher prices for consumers and reduced innovation by refiners.
