According to John M. Crisp, most accidents are caused by inexperience, not age. If you raise the driving age we will still have inexperienced drivers, we just have to make sure are drivers are experienced and responsible.
The driving age should not be raised. Many people think that teenagers are the reason there are more accidents, but that isn't true. Accidents are caused because of inexperience, not age. By raising the driving age it will just create more inexperience drivers because they will start learning something new at an older age. If we change to 18 there will be inexperienced 18 year olds.
