Anyone here ever hear of railroads? Only the most efficient way to transport goods.

Why are we keeping a fleet of vehicles and the concomitant roadway system in the mix?

That seems pretty stupid.

Why not take the oil we do have, at this relatively cheap price, and revive the rail system? Revive the streetcar system?

The amount of fuel saved over the lifetime of a railroad would be exponentially greater than the fuel saved by more marginally more efficient trucks.

And run the railroads on electricity. 3x as efficient energy wise (and uses a flexiable energy source). See EU & Japan (and Russia in a MASSIVE conversion).

Urban Rail of all types, subway/rapid rail, light rail, commuter rail and streetcars all offer 100 to 1 energy savings as well as a better "fuel" than our cars.
