I can’t remember the last time I saw a new car with these handy little windows. I was out in the MGB today, and I opened them. As a child, my parents called these ‘wind-wings’; so that’s what I call them.
What do you call them?
ETA: Merriam-Webster defines ‘wind-wing’ as ‘a small panel in an automobile window that can be turned outward for ventilation’.
