I think a racer is a racer. Doesn't make any difference if you go straight or turn corners. Drag racing will always be #1 for me, but I do enjoy other forms of motor sports, and see that each one has it's own skills. But there is just something that sets a racer apart from others and you see it in their eyes, regardless of what they race.
Speaking of racers being racers, I think the craziest ones out there are the rally guys. They've got cojones. The fans might be crazier, though, standing so close to the turns - there have been a lot of close calls.
