Kyle Busch lets MotoGP star Valentino Rossi take a spin in his NASCAR

If you're not familiar with Valentino Rossi, let me fill you in: He's Italian, he has mad hair, and he's nicknamed "The Doctor." Oh, and he's won the MotoGP World Championship seven times. Despite being accustomed to two wheels, Rossi has never shied away from four; he tested a Ferrari Formula One car on multiple occasions. Back on April 22, Rossi was at it again. Only this time, he traded the bright red F1 car for a matte-black monster -- Kyle Busch's Monster Energy NASCAR, to be precise.

Arriving at the Charlotte Motor Speedway, Busch handed over the keys to the "pazzo Italiano." As documented in the video below, Rossi seemed to thoroughly enjoy his time behind the wheel and was pretty fast in the process: “At the beginning it was a bit strange because it’s difficult to go straight," said Rossi. "But after some laps, I had a lot of confidence and I was able to go faster and faster and faster."
