I found this very funny clip of Daijiro Inada (founder of Video Option and D1GP) racing around Fuji Speedway in a D1GP prepped Toyota Chaser JZX100 the Speedracer way with his head sticking out of the sunroof:
Very funny to watch. Especially when Daijiro tries talking to the camera at 113MPh: his mouth stays open due to the wind!
At first he enjoys the experience, but after the first two rounds a while he really begins to hate it… Then he has to do the shooting again because the camera was not setup correctly and the picture is too dark!
