My brother had a huge truck for a while. Strangely, this size actually affected his driving. All the sudden he felt justified cutting the half-mile long line to get onto the highway and cut in at the last second. "Might is right" he said. "They always let me in because they are scared of this truck."

Ugh. I hope this isn't typical but I feel like it is. I told him that was awful and he just shrugged.

A bunch of people started buying larger vehicles for "safety" reasons, believing that if they were in a larger vehicle, they'd fair better in an accident. I've heard people say their spouse isn't a great driver, so they wanted to get them something bigger that they'd be safer in. Which only makes the rest of us more unsafe. My personal wish is that we would require a separate license for today's bigger trucks and large SUVs similar to what we have for motorcycles, but require an annual test to keep the license. Make it just enough hassle to keep the license, so people without a real need start to question if it's worth the effort.

Even then, a van is often better and more convenient, depending on the trade.

People think the shape of a truck somehow works better in the snow

If you work in construction you're often better off with a van anyway.

How do you know what people need? Also, who are you tell people what they need? You don't need to be in construction to get a truck. They are the best selling because they are the most versatile. You don't need different vehicles for different situations.
