It seems like some of you are trying to dismiss a good point with a superficial use of simplistic notions you learned in economy 101. Short term demand for gas may be very inelastic but if I may suggest, open back your econ book and you will also find in the long term demand notion that market agents can turn to other alternatives in the long run. Also, to the original's comment point, it seems like part of this inelasticity is in fact due to a limited mentality (preferences) rather than limited alternatives.
