The physics is the physics. The VW XL1 is lowest frontal area I know of. On other threads people complain it is small and cramped. So, we need to lower the Cd, and consider the practical requirements, rather than get overly concerned with frontal area.
The Pillbug is a huge frontal area, but with a Cd of 0.18, and the ability to carry up to 7 people, it has lower drag than almost anything we have on the road today.
The Cd is the best way to compare the aerodynamic design across the spectrum of vehicles.
