Well, thank God for government issued driver's licenses. Not one person has been injured or killed in a car accident since the government stepped in to make sure that all drivers are competent. And insured.
May not be perfect but it certainly would be worse if every 13 yr old kid was able to drive, especially without any driver ed. As far as insurance, making it a legal requirement and making proof of it mandatory for getting plates etc means that a higher percentage of drivers are actually going to be insured than would be otherwise.
No one ever said a law was going to lead to perfection. Libertarians, however, just assume that if a law cant immediately solve a problem than you might as well decriminalize the behavior: legalize drugs, prostitution, and driving under age and without insurance.
Do accidents and vehicular killings still happen ? Of course they do. There are laws against rape, murder, and stealing too, dear ; yet, no law has ever stopped such things. Tell us all that you think that there should be NO laws at all and just be done with it.
Since I was talking about FEDERAL LAWS , which have NOTHING to do with state driver's licenses, perhaps you need some lessons in logical thinking; heck, just thinking, would do, dear. :-)
