No everyone reacts well to being told what to do. I feel that maybe if they were urged to do so by appealing to them in ways that they understand may be a better way to persuade people to change. Telling a person not to do something because it is wrong does not really change a person. It's analogous to telling a drug user not to do so because it is wrong or it is hurting them. They are not going to stop.
Many people experience an internal conflict.
The internal conflict of driving tranquillity is between the knowledge that being aggressive and obscene is wrong and the underlining force of frustration and anger. Well, that would depend on the person. I think that a program like this should be more individualized. VERY relative to our topic at hand.
