Instead of computing every voxel in the virtual wind tunnel, it looks more diligently closer to the aeroform.

It's above my pay grade.
I'm not sure I am following on that. Is this a modelling and CFD or? Open source is usually free right?

I've had 2 cops follow me (both from a small town on seperate occasions) neither one pulled me over. I did research regarding it and aside from small stuff (no reflectors in the rear sides) it is legal. There isn't any inspection here, but the bumper and other crash related stuff is still there it's just covered up.
