Seriously, what if gas cost $100 a gallon? (a thought experiment…)

I am very fond of thought experiments. I like to ask “What If?” This can help me wrap my head around a problem. For instance, if I wonder how much land it would take for solar panels to produce enough electricity to supply the U.S., that’s a thought experiment. It isn’t that I think we are going to build a solar grid that is 50 by 50 miles of nothing but solar panels, nor that I am oblivious to energy storage issues. Rather, it can help frame for me whether the idea is daft from conception, or whether there is a nugget of potential embedded within.

Lately I have been thinking of another thought experiment. What would I, personally, do if gasoline was $100 a gallon?
