> Less capital cost, less labor, less wasted inventory, less chokepoints

I don't think this is a fair comparison without considering the subsidies that go to trucking, which are substantial: the interstate highway system, manufacturer and consumer auto subsidies, municipal tax codes and development that favors single family homes (further bolstering auto and road industries).

Consider that most of the damage done to roads is done by heavy trucks, but the cost is spread across everyone. That is effectively a huge subsidy.
