The challenge with going big is that the risks and costs raise substantially, while the price of having a local expert to manage both the drive and any eventualities (ie a human driver), isn't changing much... Long-haul routes are important, and shaving minutes off deliveries is a big deal. Improved driver logistics and routing are probably wildly more profitable than automation (and risks of highly visible automation failures).
