According to psychologist Jennifer Lerner, PhD, "when we're mad, we typically think we're right. Our sense of certainty simplifies our thoughts, leading us to underperceive risks and make snap decisions." (Solman, 2017).
Road rage is a perfect example of the effects of anger on snap decision making. Remember, decisions made while angry, not always, but much of the time, will be accompanied by regret - also known as coulda, shoulda, woulda.
