I rarely drive my car except for to work. Everything is within walking distance of my house, so its not unusual for me to have a full tank of gas last me about 2 weeks. I'll continue doing as I have always done.
In another thread about the cost of gasoline, some of our California DIS'ers were saying gas is already up to $2.00 a gallon where they live. Its $1.80 or so here in D.C., I guess its only a matter of time before it goes here as well.
