Are People Going to Drive Less Because of High Gas Prices?

For the past 3 weeks gas prices have increased due to hurricane Katrina.

Do you think that American drivers will drive less to save money or not? Why or why not? Who do you think will be able to drive less if they can in fact do so?
Also, do you feel that businesses that use gas as a major component to their services will suffer or increase their profit due to the rise in gas prices?
For example, pizza shops that depend on gas for their business (delivering, customers driving to the shop), will these shops gain more business due to people not willing to drive to get pizza, and as a result more people will buy pizza that has to be delivered. Or will these shops suffer, due to a lack of customers coming to eat, and the fuel for their delivery cars costing more money.
