Most drivers at that level begin their racing careers by racing go karts at a very early age. And I don't mean buzzing up and down residential streets, but real, sanctioned, organized races. By the time they've reached your age, they will already have as much as fifteen years experience behind the wheel of a competition vehicle. Starting now, you'd have a lot of catching up to do to gain enough experience. Consider, also, that a car owner isn't just going to put in a two or three hundred dollar race car unless you have SOME experience in high speed racing. If ther is a path for you, it might begin with amateur competitions, such as car rallies, autocross, and Sports Car Club of America (SCCA) events. Even then, unless you have your own equipment, you won't be able to just hop in someone else's car and floor it. I suggest to find a racing school, usually associated with a local road race track venue. Sign up for a course, pick up some skills and go from there. The path to ANY pro racing is long and arduous, but Formula Racind is considered the ultimate level of automotive competition. You can't really be too disappointed if the closest you get to Le Mans is a paddock pass behind the wall. Good luck.
