It isn't your age that is the determining factor, but how you drive. You can be as irresponsible a driver at age 18 as at age 58. At our autocross club, we had a couple of kids (ages 16-18 with a parent's written permission and with a legal license, preferrably parent present) who were driving prepared autocross cars with over 300 hp and they were very responsible and professional. Sure they might have taken out some cones or spun the car, but they learned to respect the car, and how to drive well. I encourage ANYONE who wants to learn to drive better, legally, to take up autocrossing. When I have children of driving age, you can be sure they will be autocrossing as soon as they get their license.
That being said, I wasn't ready to drive a high horsepower car at age 16 when I got my license. I would have gotten serious speeding infractions and possibly gotten into an accident.
From your comments and the fact that you have attended schools, I don't think you are a "punk kid". I wouldn't make any distinction or bias against you because of your age. It is all mentality.
The most people I see driving like idiots are people in normal cars. Tailgaiting, signaling poorly (if at all), and just basically asinine driving in general.
