Yasuyuki Kazama is a Japanese driver that used to compete in the D1 Drift Championship. In his prime, he was widely regarded as the best drifter in the world. While he was competing, he earned the nickname of “Waku Waku Kun” which means “Rodeo Clown” in Japanese. He got the nickname by driving his car while half hanging out of the window. He even got good enough to drift the car like this. Don’t try this at home, kids.
