I don't see these other people as fellow developers, but as golf-playing executives or their children.
I'm aware that not everyone here is a dev, but we mostly have similar careers.
Not everyone here lives in the US. Making SV salaries here, where 99+% of people are making under $80k/year, would be obscene. If I had access to that kind of money, I'd be putting it into better housing (penthouse?) long before ever thinking of buying a car like that.
I live on about 30% of my salary. Unless you're in the bay area or have a family to support, that's plausible (and honestly pretty comfortable) for most developers. If you wanted that car, you could have it.
