Hearing from the victims first hand would make more people actually think twice about driving drunk. Publicizing the statistics, will also emphasize that the problem of drunk driving needs to be dealt with more effectively. It's relation to traffic psychology is, that is actually makes people realize that our driving is actually the response and result of our way thinking. Our driving also reflects the kind of mood we are in. If we think about it, if we can change our behavior towards driving and when driving, we could be O.K. drivers.
Most people are in denial.
So, the first step would be is doing the driving personality make over. This will make the drivers, face the fact that we are not as good drivier as we think. I admit I am a vey moody driver. I am also very impatient, when I am on the road. I am a periodic tailgater, and a convoy member, most of the times when drivig on the LIkelike or Pali.
