A containership even more so, carrying more than 20x the capacity of a big freight train, though I don&amp;#x27;t think they have the draft to fit up the drainage ditch behind my house. Nor do I have rails.&lt;p&gt;I jest, but the long tail is a real problem with such efficiency calculations.&lt;p&gt;You&amp;#x27;re right that it&amp;#x27;s never going to make sense to have migrating swarms of drones flying above the interstate carrying packages cross-country, but are real efficiencies here at the individual level:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.cell.com&amp;#x2F;cms&amp;#x2F;attachment&amp;#x2F;4b8da4bb-42c2-4b91-baf2-d8abebef903b&amp;#x2F;fx1.jpg&quot; rel=&quot;nofollow noreferrer&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.cell.com&amp;#x2F;cms&amp;#x2F;attachment&amp;#x2F;4b8da4bb-42c2-4b91-baf2-...&lt;/a&gt;&lt;p&gt;Graphic from &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;doi.org&amp;#x2F;10.1016&amp;#x2F;j.patter.2022.100569&quot; rel=&quot;nofollow noreferrer&quot;&gt;https:&amp;#x2F;&amp;#x2F;doi.org&amp;#x2F;10.1016&amp;#x2F;j.patter.2022.100569&lt;/a&gt;.</text><parent_chain><item><author>Someone1234</author><text>&amp;gt; resulting in higher utilization per vehicle&lt;p&gt;A van can hold thousands of 2-ounce packages, whereas a drone can hold one.
