DUI's do nothing in stopping people from drinking. Most people I know have 2 or 3 DUI's. The cost of DUI's are not quite as expensive as people tend to believe. In fact, in some States your insurance will not even find out about your DUI so your rate doesn't go up. No matter how strict DUI punishments are they will never stop. Alcohol is a mind altering drug and people will continue to drive drunk.
