@Melonlity -- Exactly right and that is one of the reasons that the trucking industry hires a bunch of engineers. Hiring an engineer might seem like an odd fit at first, but it makes sense when one starts thinking about using engineers in logistics.
Engineers know how to take complex systems and make them efficient. They know how to take something with a bunch of moving parts (such as a system featuring a bunch of trucks driving all over the nation) and get them to work well together.
Check any trucking company and the chances are good you will find a bunch of engineers on the payroll.
