I started leaving the snow on the roof of my Jeep to get an idea of what the flow did on top. Looks like the air re-attaches about 1/3 of the way back on the roof.

Try looking at the shapes that snow gets drifted into against other objects besides just on cars. And also take into account the liquid density of snow. Wet snow will pack and freeze and the shape we see may not be so much the result of aerodynamics as of imobility. While dry powder snow flows quite nicely and should leave some interesting ideas to test.
Oh wow, that's awesome! You can even see how door handles mess with your aero.

Yes if your car aero is perfect there would not have any snow left after test. I would be interesting to see for example aerocivic do the similar test. he has pretty good Cd but pretty rough surfaces. So the pockets should fill with snow.
