The answer of course, is that the government through the police, must always know your current address so that they can control you. In cases of disagreement brought before a judge, your guilt is presumed, and self-incrimination is made a requirement, as you must sign the traffic ticket. Most terrorized citizens simply pay money they do not owe just to avoid the stress of prolonged bureaucratic harassment that occurs in the courts. Harassment that is always dispensed by a corrupt judical government employee and not an impartial arbitrator of truth and justice as mandated by the constitution. Let's dispense with one popular fallacy.
Traffic tickets have nothing to with highway safety.
We want to emphasize that traffic tickets and traffic law enforcement are not synonymous, and the first should not be considered a necessary component of the latter. State and local governments learned long ago that traffic ticket financial sanctions have little deterrent effect on motorists. Some might argue that fines could be increased to the level that motorists would be sufficiently intimidated to obey the law. In reality, large fines increase motorist resistance to paying high fines and instead, they demand a trial. Trials take all the profit out of their system.
