First, let’s look at this literally. In some states, a 14 year-old can legally take a 4000 pound killing machine out on an open highway with little or no supervision.
It should be no surprise that the correlation between legal driving age, graduated driver licensing laws, and the teenage driving fatality rate in each state is staggering. In some states, all you have to do is pass a simple (5th grade reading level!) test, navigate around some construction cones, and POOF! You have the RIGHT to drive.
Unfortunately you also have the right to die young.
