drving age at 16 or 18

I think that the driving age should be 16 and not 18 for so many reasons. If the driving age was 18 then a lot less people would have cars. And many teenagers would have no way of getting to school. You would not be able to drive places and go everywhere. Also many car dealerships would not have as many customers because many of their income is first time car owners as in teenagers. Also it helps out parents too because now their kids can drive to the store or bug up their younger siblings without the parents having to stress out about it everyday.
