Um no. Are you claiming that high gas prices will no impact on demand? That is not what Econ 101 says. Most trips are discretionary. The traffic volumes are far higher from Friday evening to Sunday evening than they are during the workweek. The traffic starts backing up in central and southwest Washington over 100 miles from Seattle on Sunday afternoon.
I never suggested that high gas prices have no impact on demand. I said I don’t know anyone personally who is changing their driving habits right now and I too am not changing. Econ 101 also says that fuel is relatively inelastic. However, rising oil costs affect many things besides just personal driving.
If you’re on a fixed income then those people are more likely to change their plans. But even discretionary trips — I don’t think too many people are now going to choose to stay home instead of go to the mountains because it’s going to take an extra $15 to fill up a tank.
