Gas has gone up a lot in the past 10 years.   But at the same time  cars have become more efficient and due to general inflation costs have gone up in general.   If adjusting for inflation then what is the trend in spending on gasoline per mile driven given these 3 variables?   Well glad you asked, here's a chart :

The figures are in 2010 real dollars.

And in table format :

 I got the data from :
Average auto fuel economy in MPG from the DoT Bureau of Transportation Statistics Table 4-23: Average Fuel Efficiency of U.S. Light Duty Vehicle
Average gasoline prices from the EIA
Inflation data is from the CPI report Table 24
