It's just physics, not a moral argument. Drag increases as a function of velocity squared, and increasing speeds above some point requires more energy per mile.

Drag increases as a function of velocity squared, and increasing speeds above some point requires more energy per mile. https://en.wikipedia.org/wiki/Drag_equation https://en.wikipedia.org/wiki/Drag_equation If there isn't a lot of traffic on a section of road, people can move through that section faster at higher speeds, so there can be less congestion. On the other hand, if there is enough traffic, high speeds reduce the throughput of a given section of road because braking distances as a function of speed increase faster than speed. https://one.nhtsa.gov/nhtsa/Safety1nNum3ers/august2015/S1N_Speeding-August2015_812008.pdf https://one.nhtsa.gov/nhtsa/Safety1nNum3ers/august2015/S1N_S...
