I'm a bit late on this thread, so I apologize if this has been answered before... The air fluidity from the front clearly showed a LOT of turbulence in the sidewall midsection. If you inverted your design, you'd reduce that drag to a fraction of what it is.
Granted, you'd increase turbulence at the rear, but I would think that it would be a much smaller at that point.
I accidentally ran CFD the simulation backwards on my first run (for some reason the coordinate system was/is reversed).... While the oil flow lines looked nicer - there was slightly more drag (but only slightly).... But, even so - we wouldn't fit! It's really hard to fit a human - pointing forward - with pedal path considerations AND be aerodynamic The prone position (laying on your front - head first) would be more aerodynamic, but the prone position isn't as intuitive as sitting - a primal task
