My in-laws have a van that can out-pull my pickup. Partly due to my trucks age and how heavily it has been used over the years, but their van isn't exactly a pushover.
And they have their own pickup that is only a few years old and it can't tow their camper very well. They use their van whenever they can.
Most days I don't need a truck. Most days I don't want a truck.
But that's what I've got and I can't exactly just buy a new vehicle, or simply change jobs to one I can cycle to.
I'm a minority though, for most people it's compensation for insecurity or attempted status symbol. Around here we call them "pavement princesses" because they never touch dirt and likely couldn't navigate a back yard with its current driver.
