Operational efficiency. I’d compare it to Amazon vs usps. I pay for Prime which is like paying for Kaiser insurance, Amazon’s fleet is an just extension of Prime membership to improve my experience as a shopper and completely under their control (I can get 3 deliveries in a day on Sunday). USPS is less innovative because they less incentives to “wow” me.
