All vehicles have them, they just hide them from normal view. Sedan's have them from the cabin into the trunk area, always in the rear of the cabin wall. You force air from the HVAC into the cabin at the front of the cabin, it has to go somewhere. Also, temp changes, ever wonder how your windows don't blow out on a hot summer day? Or, how you can open/close your door?

My Jeep TJ does not have those pressure relief louvers in the tailgate, and has a hardtop from a different model year that didn't have them built into the top. For that reason lacking any pressure relief, it's harder to get a solid close of the doors without extra slamming effort. So yeah as mentioned, they help with that sort of thing relieving the pressure.

Helps circulate the air in the cabin after Taco Bell.

On pickups they can usually be seen on the back of the cab and hidden by the bed.

Lots of cars have these vents, but they're usually down low, hidden behind the bumper cover. Ford could've done that with the Bronco as well but it would've been a bad idea when it comes to water ingress.

They resemble flood vents in homes in flood zone

That actually would have been quite difficult for Ford to do with the bronco because the bumper is entirely below the body and floor, unlike a typical sedan or wagon where the bumper cover is actually covering the lower section of the body.
