Kach : that's an interesting image.
I remember seeing those same patterns on Svens' anal probe after he tested it in the snow.
Two symetrical areas that cleared down the sides, with the center section having snow remaining.
He had guessed that this showed that there were two vortexes along the sides of the rear glass.
Looking at the CFD image here seems to confirm that.
I miss that guys humour.
