So as you may see, people are really really stupid about laws. The largest problem with law creation is that it mostly comes out of litigation, or the act of filing a law suit against someone else.
For instance the law in Long Island as written above was a direct result of one surviver suing another person for driving the wrong way under influence, so instead of realising it should be illegal to drive the wrong way fullstop The state simply decided to stop those under influence doing so. If you'll excuse my britishness it's total codswollop.
