There are less than 4 million miles of road in the US. At 1$ per mile you can send a truck down every one 6 days a week for  1.3 billion a year. (Note, there would be some backtracking but also some roads are avoided.)  FedEx&#x27;s revenue is 45 billion a year so the last mile is not a problem as long as the volume is there.<p>On top of that if you live in the middle of nowhere they simply don&#x27;t deliver to you.  So, if more people moved to the desert for whatever reason there costs stay more or less the same.<p><a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Transportation_in_the_United_States" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Transportation_in_the_United...</a>
