80% less gas!

Chevy Volts traveled 15 million miles in their first year on the road, and 10 million of those miles used no gas.  (According to Jeff U'ren on the Chevy Volt Owners facebook page)  Assuming 37 miles per gallon for the 5 million miles on gas, that means the Volts got 111 miles per gallon over the 15 million miles (3 x 37).  Compared to the average U.S. car's 22.4 mpg, that means the Volt uses 80% less gas.  Given all the oil spills, air pollution, wars for oil, global warming, and the high cost of gas, it is time to make the switch to electricity for all transportation.
