This simply doesn't scale. We have this happening to an extreme in the US because cities are spread out and people are already used to drive to get what they want (so roads are well-built for deliveries), but the more density you get the less this becomes practical (O(n^2)). Large cities everywhere else in the world perform distributions not point-to-point but point-to-hubs, where people are used to go out for a short walk to get what they want from their local grocery store, electronic store, restaurant, etc. I think we'll see more and more deliveries being made for semi-large items though.

Looking at my history, I made an average of 60 orders per year through Amazon while living in the US, an average of 4 orders while living in the UK, and an average of 5 orders while living in France.
