We are building a just-in-time distribution network on top of USPS (Bottomless - YC W19) We're able to deal with their slowness because we predict demand in advance using data from a smart scale. It's quite astonishing how unreliable USPS is. We frequently see packages get routed to a totally incorrect part of the country, derailing shipments for several days. Also, it seems like even USPS doesn't know when their packages will arrive. The estimates they give are worse at predicting arrival time than just inputing distance into a simple regression!
