I like to call it "poor engineering" and there are many forms of poor engineering I've seen. Following the analogy... painting the bottom of the bridge in same color as the terrain. Then repainting because there were color differences.

Spending time and money looking for lighter materials even when the bridge is designed to support a lot more weight than traditional time tested materials. Justification : "Maybe cars will get heavier, and bigger saving 3 pounds is a good pursuit"
