I think thorstadt was talking about latency: just like express messengers switched horses in the pre-telegraph age, trucks could be handed from driver to driver to keep them running without mandated breaks. With half-workday legs, a system like that could even allow many relay drivers to get home every day despite driving long-haul loads. My gut feeling is that this could work in theory, but would never evolve in the framework of a free market economy (whereas a planned economy would tend do everything by train).
