Gas prices haven't changed our driving habits at all. Gas is such a small part of our monthly outlay, it would have to rise quite a bit more before I'm going to change anything.
Seeing as how everything is supply and demand based, it amazes me how people and politicians complain about the prices while not letting the oil companies drill more and build more refineries... Go figure...
Really, there is plenty of oil to sustain the US. It's not like the oil crisis we've experience in the past, were the supply was very low, driving the price up. The main reason oil is so high, is our weak dollar. It makes commodities like oil, gold, steel, ect more expensive, because your dollar isn't stretching as far as it used to. If the dollar was higher, gas prices would be lower. Not $1 a gallon low, but much lower than they are currently.
