The scientific justification behind our current age limits are quite limited and the real reason is more based in tradition. For driving in particular, I wonder to what extent it is based off of being able to hold a job. For voting, I wonder what extent it is related to school graduation. Also, as a side note, generally kids can legally drive at any age as long as it is done on private property and isn't so dangerous it constitutes child endangerment. If you talk to farmers you'll find many stories of kinds driving trucks on the farm when they were under 10. Even more fun, some states don't have age limits for kids driving on public roads as long as it is farm equipment. Those laws might be one tragedy away from being rewritten, but until then it is an interesting thing to consider when discussing the relationship between legal age limits and our scientific understanding of mental maturity.
