I understand frontal area.
I talked today to a guy with a phd in aero crap. I asked him if two shapes in close proximity, with some overlap, will have a lower Cd then the same objects stacked on top of each other.
his response: Of course. That is pretty fundamental and anyone who has done actual rudimentary modelling understands this.
so, again, I ask. Do you still stick to the .40 number? The guy I was talking to said I should be comparable to a Prius at worst for Cd, and my area is obviously much smaller.
