One day you will be pulled over for a minor traffic infraction. The officer will run your license and one of these tickets may have caused a warrant to be issued or your license to be suspended. You will then get a free ride to the nearest jail and your car will be impounded. After paying all the fines and fees, you will be released to resume your life.
Or you attempt to buy something on credit and you are denied because a collection agency, action on behalf of the entity that issued a parking ticket, has placed a negative mark on your credit report. They then start calling and hounding you for not only the parking ticket fine, but other expenses and they now want 10 times the original fine.
Or one day you park your car legally only to come out and find that it is gone. A call to the police results in you being told your vehicle has been impounded and will be held till your past due tickets are paid. Plus you get to pay for towing and storage too.
Those are some examples of what could happen to you. There are many others.
It's gonna be real fun
