Kazunori Yamauchi doesn't just make racing games. He races cars, too.
In this clip, Yamauchi is behind the wheel of a Lexus IS-F race car, doing a complete lap at the 24-hour Nurburgring circuit. The vehicle is in the upcoming Gran Turismo 5. Call this research.
No crashes, engine noises, European track. Watching this video is like watching Gran Turismo.
Huge respect for Yamauchi's dedication to racing and racing games. (If only he could release his games in a more timely fashion!)
