> aerodynamic drag is by far the biggest source of efficiency loss. Rolling resistance is a bigger source of loss under 30 mph. > The most efficient traversal for a fixed time interval is fast acceleration / deceleration with a reduced top speed Wouldn't it be increasing speed for half the trip and decreasing it for the other half?
