My wife and I both use the “thumbs down” method. It’s funniest when we’re both doing it to some ass-hat, while riding together.
It often de-escalates the person though, as if they don’t know how to respond. They usually just make angry gestures and mutter (probably obscenities) to themselves, but their rage usually chills out a bit. It’s almost like you make them aware of how childish they’re acting
