How about a move for a 55 MPH speed limit. It not only saves gas, it saves lives. I don't have the studies at my fingertips, but I remember reading about the number of lives saved by the 55 MPH limit during the '70's "gas crisis."
This summer I drove across the country, and was able to use my ScanGauge to test 55 vs 65 MPH on long stretches (in five mile stages).
Driving at 65 consumed 21% more gas than driving at 55. Your mileage may vary, but it sure would save gas.
