If the object is simply to relieve tension, then, sure, exercise is fine. But, if you have the good fortune to have to come into contact with people beyond your control, you just can’t beat destroying things. I think there is good reason for that; but I will save that for later. Consider the number of times you witness someone driving in such a way, it is obvious they are trying to cause an auto accident. I know of more than one incident when someone quickly changed lanes, for the sole purpose of causing the person behind them to run into the car in front of them. It would probably be safer to take up a sledge.
