Perhaps trains beat road transport efficiency to a similar degree.

This is why European cities had so many canals back in the day.
classic volume grows faster than surface area.
also, fuel is a huge cost (maybe even the main cost), and drag has a >linear relationship with speed- so the ships will slow down based on fuel prices.
