&gt; Isn&#x27;t using containers much more efficient anyway, instead of moving the whole truck?<p>The core problem is that freight companies in Europe standardized on the Euro Pool Palette (EPAL) but ISO containers worldwide use the non-metric US measurement system - thus leading to waste of space and potential safety issues (sliding palettes due to slack space on the floor).<p>Trucks, however, are fitted to the metric system and can safely transport EPALs, so you&#x27;ve got next to no alternative.
