I would expect the delivery vehicles to cost a lot more, but those higher upfront costs reduce the ongoing costs (maintenance etc). There would be an incentive to maximize utilization as an idle vehicle earns no money. A vehicle owner would want to deliver on behalf of many businesses, which allows combining multiple deliveries for better utilization. Software would allow for a lot of optimization in routing, pickups, delivery and transfers.
