A family member was a civil engineer in the Federal Highway Administration for many decades, specifically in concrete pavement design, and remained an a technical career path the whole time. He had many war stories to tell related to the trucking industry. In one, they had developed a scale that could measure the weight per axle of vehicles on the roadway without requiring the vehicles to slow down. They wanted to embed these in a few places to prove how bad things really were with overloaded trucks. The trucking industry bought off some congress critters who would only allow them to put the scale at one clearly marked location on an interstate, in one lane. The lane next to the scale lane was crushed by all the trucks driving in that lane to avoid the scale.
