Oh, gas prices in the U.S. absolutely change daily, sometimes by 20 or 30 cents (though usually less than 10)--at least, in most states. Some states (like NJ, as I recall) have heavily regulated gas industries, and are limited to weekly price changes, for example.
I was always interested in seeing a graphical summary like this.
It would be even more interesting if such a map could overlay information on state and local taxes, or regulations (as mentioned by Scott above).
What I'd be really interested in seeing are the base costs of gasoline, without all the local taxes. Certainly, that doesn't reflect what consumers pay at the pump, but it would be interesting to see if/how prices change as a function of distance from shipping routes, etc.
I've always wondered if there were certain areas in the US that have higher gas prices then we do and now I can see a simple indication that there are. Awesome map and a pretty good reference for when I'm taking road trips :o)
Neat find. I wonder if the wholesale costs for gasoline vary as much as the retail costs? Maybe there are substantial differences in transportation costs that get magnified when you add in the retail costs related to local taxes and real estate values.
