I apologize if this is something that has been asked/answered a thousand times, but I can't seem to find a straight forward answer... What exactly is the difference between road course racing and auto crossing? For a while I was under the impression that they were just different names for the same thing. I've now realized that's not the case, but I'm unsure of what the difference is. Sorry, I'm sure I sound like an idiot, but I gotta learn somehow, right?
