Those exact same words (with rider replacing diver) were the first ones uttered to me by my Motorcycle Safety Instructor when I first took the course back in the the 90's. He was an ex-CHP officer with ~1 million miles under his belt, and had a lot of stories, gruesome and glorious.

It was a great class, and he was a wonderful teacher. Scared the foolhardy, sobered the romantics, and conveyed a career's worth of lessons on riding safe. I've been accident-free since starting in '94, and I genuinely do think a large part of it was his initial, excellent instruction.
