@Draug .. first of all, I raced sprints, and second of all, I raced on a number of figure-eight tracks (as opposed to four left corners or road courses, both of which I've raced too). Figure-eight tracks are a thousand times more challenging than driving. Why? Because you're going 90 MPH and trying to avoid that person running the metaphoric stop sign for two hours straight. It's scary, and it certainly makes you prepared to drive on a road.
A fourteen-year-old is equally capable of racing as a 40-year-old, and the reason I say that is that maturity factor. Racing, especially drags and drifts, is easily the most dangerous sport that Joe Average can take on. Anyone can do it to a point (obviously professional racing is different). The thing about fourteen-year-olds is that they get into a car to race and expect to wreck or win. A 40-year-old gets in and expects to take home more money than they bet to enter, and to do that, you have to finish. Like my dad always said, the old man that drives 150 yards in the middle of the fairway scores better than the kid that drives 250 onto the adjacent fairway. Same goes for racing.
That said, in general, you're exactly right. There are rules to roads, and because many people don't follow them, it's often those that DO follow the rules that cause the danger. However, there's also the fact that you're steering, like 2WL said, between one and two tons (in my case exactly two) of metal that can kill a person before they realize what's going on. I have - well, had - a friend that was killed on his bike because someone ran a red light and hit him. They left the scene and they're in jail for manslaughter for the years to come. I know exactly who that person killed, but I don't know what his future held, nor does anyone else, and I honestly feel like that took an awesome kid, but we'll never know. That's the danger driving poses.
Still, that guy was 36. He'd been driving without incident for 15+ years since he could get a car. He'd only had a few tickets, but he was stupid once, screwed up, killed someone, and ran off. If he'd stayed, he probably wouldn't have gone to prison (he wasn't drunk), but either way, the end is the same.
