Doug Calkins teaches driver's ed at Muscatine High School. The high cost of gas affects his ability to teach students how to drive on the interstate and around time. He spends 4 hours a day with students driving by Loos gas station and the local BP. Doug is accutely aware of changing gas prices. I think Doug is rational so I'm going to assume that he prefers more to less. For example, Doug prefers more free time to less. He prefers more income to less. So it follows that he prefers to drive more than less.
How would lower gas prices affect Doug? He'd drive more. If everyone behaved like Doug, then there would be more pollutants, more congestion on our streets, and more maintenance needed to keep our plant both green and efficient. In this normative discussion, maybe the higher prices are good and everyone should understand that the economy is working to distribute gas efficiently.
