Why American and European Trucks Are So Different

As an American who has spent a lot of time driving in Portugal, Spain, and France, I can say it took me a while to get used to mostly much narrower roads, and this was in compact cars lol, so I can't even imagine how often a large American truck would have to stop and navigate around a lot of different ways, or at the very least feel constant anxiety of not being able to clear certain angles and turns.
I'm fascinated by the fact that the majority of the difference is geographical. Europe has much less usable land that isn't mountains to build things like roads on than the United States, but they have a third more people. It's fascinating to see how this affects everything, including truck design.
I like how European trucks can adapt to any type of road, making them more versatile in use, but I absolutely adore the aesthetic and ring of power that American trucks have. I'm not sure what it is about that long nose that appeals to me. And the amount of customization done to these trucks in the United States is incredible.
