IME it is often the female pushing for the bigger vehicle. My ex-wife kept pushing to upgrade our Subaru Outback to something bigger and we only had 2 dogs and no kids in the suburbs. Similarly, my wife hated my Chevy Bolt because of its size. I think folks stereotype big vehicle purchasers as males looking to compensate for feelings of inferiority, but from what I've seen(beyond just the examples given) is that this isn't really true. I'm sure it sounds good to folks looking to denigrate people with vehicles that are deemed excessive but is trite and silly.
