$20 gal gas?

OK are we ready for $20/gallon gasoline? It would mean getting our cars to be a lot more efficient and driving shorter distances. Perhaps we can find more oil in the deep ocean. Converse it would mean most of our money will be spent paying at a pump.

Perhaps we can dump the pump and go with electric transportation, as in electric bicycles and maglev trains. The electric car is both expensive an inefficient.
