Same logic as:
1. Dogs have four legs.
2. This animal (a cat) has four legs, therefore it is really a dog.

1) The LEAF has a pseudo-Jaray roofline failure, just as Kamm/ Fachsenfeld investigated at the FKFS.
2) The solution was to extend the roofline, following an extrapolation of the initial contour, to the very end of the vehicle, filling in the turbulent void.
3) This is the reason your Insight has the roofline that it has. If it were mutilated as with the LEAF, you'd experience increased drag and lift.
4) If carried to it's conclusion, the LEAF becomes a pumpkin seed, just as Kamm, Lay, and Jaray arrived at. True 'fastbacks.'
