Driving age being raised

In class, I decided this is my for sure research topic. There are so many things I can do with this paper. First of all, I know that in South Dakota the driving age is 14, but I have no idea why. So, I can learn while I write the paper which I feel will be very beneficial. Some questions I have to answer in my paper are: who put it so low, what are the rules with driving age at 14, why did they put it at age 14, how do we change it, how much does it cost to change, # of deaths in other states compared to ours, how much education before a license is given, causes, and statistics. I am going to try to prove that at age 14, kids's brains aren't developed and are still very immature which is never good when being behind the wheel. Going through 2 months of a driving class and taking a driving and written test just doesn't seem to prepare a child enough in my opinion. I will give the statistics about how many deaths have been caused by young teens compared to other states. The rate at which a female and males brain are developed. How could we change this law. There are many things for me to think about, but right now I have my topic, questions, and can start trying to find information for my paper.
