Alkimia,

You are asking a broad question here, so without more specifics I don’t know if you are asking about the car movement itself (camera movement, animation, wheel turning code, etc.) or how the video appears in the reel as an animation wireframe, so I’ll flip a coin and take a guess.

If you notice in Yoshiomi’s video starting about 0:35 toward the bottom left you can see the Softimage XYZ axes moving. It appears that he’s playing back the animation under a Camera view and simply capturing it all with “screen recording” software (maybe Camtasia?) as it played inside Softimage as a wireframe. In his real time car section, starting around 01:07 of the reel, the whole lower part is cut off and you cannot see those XYZ axes moving, but he’s still doing the same thing there too. In fact, if you look close you can see one of his other Softimage cameras in the upper right following the car as it moves across his road track. Hope this helps. :)
