even long-term, it's tempting to think that synergies and market consolidation would lead to higher utilization rates through stacking (making multiple delveries at once), but indications from current players in the space are discouraging in that regard.
last-mile logistics is an exceedingly tough nut. i think it's really going to take a wholesale reconfiguration of cities around much more density and mixed-use where shared industrial kitchens and warehouses can make the synergies work out, but of course that's decades in the making.
