Very interesting article! I note a couple of things:
1. A car has to deal with ground planes and there is no mention of them in this brief article.
2. Most interesting to me was the red and green areas of the graphic. The article mentions that the red lines represent "classic" computation of separation. The green lines represent the "new" theory. From the graphic it sure looks like unseparated flow exists much longer than we had thought SO LONG AS THE SHAPE TRANSITION IS GRADUAL. Don't know that "final" angle on the sphere, but it could be 30 degrees or so.
