I think it’s an uglier side of our society that people automatically assume people with money are bigger dicks than the rest of us.
I’m not sure that is the case here. It’s the model of car as much as the cost of it. I have nothing against normal Rollers & Bentleys in general, but that 4×4 thing is inutterably loathsome. Most other heuge cars have something about them, a presence, a top speed or a beauty.
That thing is just a butt ugly ignorant way of showing how much money and how little class you have.
In this case I think it is a perfectly valid assumption to say that the person driving it is a bigger dick than the rest of us.
[Partly tongue in check, but partly I genuinely do think that]
