We don't care, we're driving Cadillacs in our dreams
This line serves as the tagline for Lorde’s Tumblr, so it deserves some consideration.
People like her that don’t want to be “royals” are perfectly content with having crazy dreams and fantasies that don’t match up with reality. They would rather dream about the lavish lifestyles of “royals” than actually live like them. So they “drive Cadillacs in their dreams” and continue with their ordinary lives.
