Well, fuckwit, good job on proving that you know how to multiply a couple of constants and volumes together, congrats!

Consider the amount of energy that goes into welding a large automobile frame, casting high carbon conrods and crankshafts, producing all the plastic that goes into the 3100lb ~~clown tank~~ dodge ram you drive since you're no longer safe on two wheels.

Holistically, quite a lot less energy goes into production of a motorcycle, and furthermore is tremendously easier to recycle in comparison. The much lighter mass from a smaller frame means less tire particulate, less brake dust, and equally important, less time idling in traffic because of lane splitting.

Quality thinking in systems analysis is why engineers make money, versus fuckwits who merely multiply a few constants.

Fuel pump pressures need to creep up to afford DFI (direct fuel injection) which has made up a lot of modern ICE efficiency and emissions improvements. The real solution long-term is electric, but energy density in the batteries needs to creep up a bit, which I'm waiting for with Samsung's new solid state batteries.
