> I'm really at a loss to understand what the transportation waste means. Sure, you also need to propel the mass of the vehicle. Total work done by the vehicle / total energy contained the fuel. A small combustion engine is a very inefficient converter of energy, so it's no surprise that it's only able to use 1/4 of the available energy. The rest is lose as heat (as well as minor losses such as noise and slippage).
