Utilization of private vehicles scales with income, not with population density. HN just all tends to live in "nice" places so they never see people using their vehicles to the max. This is true for all vehicle classes, not just pickup trucks.
Fashion is about signaling not whatever you happen to agree with.
Tattoos aren’t universal, what’s acceptable for Army special forces, goths, gang members, etc are all different. So, good or bad only exists in a specific context it isn’t something that any person can judge universally. Someone really can define good as whatever pisses people like you off.
If people decide to broadcast their opinions about the world using cars, they certainly can; but I don't think that kind of behavior can be called "fashion". Ideology, maybe.
Political affiliation is definitely part of social standing and the degree to which such signaling impacts how people talk, dress, and what they buy is very much fashion.
As you venture out into the world you will also find trucks that are clear political statements. You might be right that an individual cannot own a truck for both fashion and political reasons (although I'm not sure I agree), but just because some people use trucks for political statements does not mean all trucks are political statements. Some trucks can be used for fashion without crossing those who use them political statements.
I happen to think that most modern trucks look incredibly stupid, but that's because their design language isn't intended for me. It's intended for people who have different fashion tastes, tastes that approximate political positions that I don't hold. In other words: the truck itself isn't a direct political statement, ordinarily; it's an efficient means for signaling politics through fashion.
As a Canadian living in the heart of supply management (i.e. state ownership of the means of production) country, where supplies are provided by the so named and literal Co-op (i.e. community ownership of the means of production), trucks are very popular. In part because they are useful tools in carrying out the business within that socialist system, but also because outsiders emulate to try and convey similar social standing.
If there is a political statement to be found in there, which may be a stretch, to me it would be that trucks = socialism. But when I look beyond my bubble, I'm left with the impression that trucks are, if anything, especially stateside, a statement at the compete opposite end of the spectrum.
What approximate political position do you believe is inbuilt into the design of modern trucks?
99% of trucks are not that these days and that may be being generous.
Also... spend half the money on a beater truck and the other half on a civic so you dont take up the whole damn road on your commute to your office job and kill me when your comically oversized vehicles rides over mine in a car crash. I am tired of seeing $70,000 trucks without a scratch on them being used like they are a commuter sedan, its selfish and stupid.
Pickup trucks are the opposite of fashion. There are to cars what Crocs are to shoes.
