If you will be true to yourselves, the only real reason that MOST drivers obey a tin sign on the side of the road that has the number 55 painted on it, is because they fear the State Troopers will give them a ticket. Very few will obey any Law simply because it is the Law. Every G-d himself set the punishment for breaking any one of his first five of his commandments as being Death (either physically or spiritually, or both).
