I don't think it's malicious in most cases. As a counterpoint, most family members I know with absurdly large cars, either dimensionally or in terms of seat height aren't very confident drivers and the large vehicle makes them feel "safer" especially if they have kids in the car. I recognize it's not always the case but they didn't buy a large car to lord over other people on the road they did it for emotional piece of mind. I'm willing to bet a lot of people however wouldn't be willing to admit that that's why they prefer a large car out of some perceived weakness or the like.
