The interesting thing in the US is that a lot of pickups, possibly most of them, are purchased for regular daily driving. None of the people I know with pickups have trailers.
I love seeing Ram 6000 Max Diesel Rampage Pros who’s sole job is going to work and Walmart.
What do you mean daily driving? Like commutes? That wouldn't make any sense.
That some people buy them and don't really need them has zero relevance on whether any people have need for them.
I find it somewhat amusing that this attracts a lot of ire, but most of us would prefer a 2,000+ sq ft suburban home with a lawn when we could live comfortably in a 500-700 sq ft apartment, like people do in most European cities.
Ultimately, life in highly developed countries is largely about the wants, not the needs, and different cultures emphasize different wants. The tech culture of the SF Bay Area doesn't glamorize big trucks, but it glamorizes making millions of dollars with no regard for privacy or social impacts of the tech we build.
American trucks are built for towing -- it's one of the reasons they are so big and heavy and expensive -- so I get where the "trucks are for towing" wisdom comes from.
But it's still funny to me. Because in my mind one of the main perks of an open bed is that you can do so much before having to deal with a trailer (which are super annoying, especially in cities, especially without off-street parking).
Which I guess is just to say: maybe there's a market for a truck that can't tow much, because maybe there's a portion of the market that wants an open bed but doesn't need to tow a massive camper or whatever.
