This is a CT scan of a wind-up pace car. Note the wind-up key on the port side (opposite the viewing angle). The driver is easily visualized behind the steering wheel. Perhaps the most interesting part of this image is the spring whose loose coil can be seen directly to the right of the driver. The spring is connected to the drive mechanisim. The relationships of all these parts can be more completely appreciated by viewing the movie.
