This probably isn't for cities. I was at a conference a few years back where Prime Air gave a talk. It was quite a vague talk, but admittedly it was hilarious watching Takeo Kanade grill the speaker on technical details that he refused to elaborate on. Things have no doubt moved on, but they were talking about use cases like delivering to rural areas where people have big gardens to land in. So potentially places where sending a delivery truck miles out of the way would be expensive (e.g. a 20 minute detour to one house). That's where the interesting applications of drone delivery are.
That drone is pretty big, and they're getting extra lift out of the wings which conveniently double as prop guards. Flight time is presumably at least an hour, if it can get something to a customer in half an hour (and has to get back). You'd need quite a few since each drone can therefore only make around 10-20 deliveries a day if they swap out the batteries when it lands. 30 mile round trip range is pretty decent. Also on size - you need somewhere to land it with a few metres wriggle room either side. There's no way that's going into a built up area.
There's no point doing drone delivery in urban environments, the safety case is insane and you're competing with excellent existing delivery channels.
