Dave,
I ran your temp.world file and experienced the same issues. However,
the flickering occurred on the body of the car chassis rather than
the environment.
I believe your problem is due to the fact that your light source is
so far away from your car model. By changing the light source in the
world file to:
<model:LightSource>
<id>light0</id>
<xyz>4304557 308767 100</xyz>
</model:LightSource>
I was able to removing the flickering. I think that because your
light source was so low and distant, OpenGL was interpreting shadows
cast by the wheels in an unexpected manner.
