"on-demand logistics which is a totally new field at this scale" I've heard this argument before, but how can this be taken seriously? Take DHL, or UPS - they do orders of magnitude more (in transactions) than Uber does, and I know it's not exactly the same, but I'd even argue that any parcel service is a lot more complicated than Uber. Hell, even the tiny postal service of my country ships the same amount of packages each day as Uber has rides. The tech side of Uber is (dare I say it!) trivial (well the 'ride sharing' part, not the AV research side). It's the regulatory and plain business model angles that must be costing them.
