The social cost of inconsistent laws and regulations

When we see laws and regulations vary by geography, that teaches us that they are arbitrary and not necessarily based on facts or logic. When in one state, driving laws are different from the next, we learn that perhaps neither are correct. When regulators establish one set of rules for utilities in one state than in an other, we see that these too are arbitrary. For many people who see multiple laws and rules as based on whim or lobbying, they conclude that perhaps others are as well. In the end, this weakens respect for law and encourages people in their professional and personal lives, to skirt or break the law.
Unfortunately, most of the law-makers have not had the experience of living in multiple places and seen the absurdity of it all, and even less likely that enforcement officials have.
