I believe that the driving age should be raised because 18 to 21 year olds are far more responsible then 16 to 18 year olds. Therefore more responsible drivers on the road less accidents.
I believe that the driving age should stay the same because collage students and high schoolers couldn't drive to school. Therefor the teens wont be able to go to school and not get the education they need.
Its not the age of the person its the lack of experience. So it would only make 18-21 year old in the risk of the same stuff as the 16 year olds today.
