> instead of constantly starting and stopping to access road-side mailboxes Q: What's the (average) distance between deliveries to road-side mailboxes? I'm thinking of the average driving time between them, compared with the time to get out of a vehicle, put mail in a mailbox, and get back in the a vehicle... I know "mounted delivery routes" sound and feel more efficient, but just how much more efficient are they actually? We should note that USPS letter volumes are falling (just like everywhere else in the world) and somehow parcel/packet delivery services do not need to have "mounted routes", the delivery crew appear to be able to just get out of their vehicles(?)
