The bottom line is that while humans may not be able to make much energy, automobiles are terribly inefficient, and waste a LOT of energy.
That number seems way off. Foreign imports account for two thirds of the US oil supply. If biking to work one day week reduces imports by half, then two days a week would eliminate imported oil. Three days a week means no oil needed at all.
Edit: Now I see your edit. Persian Gulf imports (Saudi Arabia , Iraq, an Kuwait) account for about 25% of foreign oil so it makes more sense now.
