Speaking of truck driving, I did that for several years a couple~few decades ago, and there is more to it than many know or appreciate.
First getting the knack of clutching through the gears, on the larger rigs especially. Also developing that sense of perception about what's behind you, what you are pulling/towing, especially when doing turns, passing, and backing up to a loading dock. Then there is the thing about the driver is responsible for having their load secured, whether it's cartons and/or pallets stacked in a box trailer, or items strapped down on a flatbed trailer. And if it's a refridge or freezer load, having the unit set to correct temp and fueled so it doesn't quit is another concern. And of course, the CDL and periodic health checks required.
More recently my manufacturing experience started with composites for aerospace, carbon fiber, fiberglass, and kevlar; production and inspection. Most recently was with a firm where much of our product line was fiberglass (and other composites) for use in FGD - Flue Gas Desulurization systems at coal fired power plants. EPA set the emissions standards back in the 1980s and most older plants had to convert to FGD systems as well as newer builds. As QAI I interacted with assorted designers, engineers, and other customer QAIs. It was where I got more first hand knowledge on dealing with CO2 as byproduct of production systems.
