1) M_a_t_t, this one is for you!
2) For people following the Aerohead / template debate, as far as I can tell, this video covers how Aerohead thinks the aero of
all sedans behave. (Primarily, because back in 1987 - the year of the textbook Aeroheads most often cites - this is indeed how aero on sedans was.) But things have changed...a lot. So don't use this video to modify modern-shape sedans that have attached flow.
