I ordered two small items from Amazon one afternoon around 3:30 — about $38 worth of nothing important. I was told to expect them between 5 and 10 that same night. I doubt I could've driven to a store, found what I needed, paid for it, and gotten home again faster than that.
Which got me wondering what it actually looks like out there on the roads to make that kind of promise possible, night after night, all over the country. So a couple of characters and a long red convertible went and found out.
