Not necessarily. This is not a long, straight wing shape. It is more of a meld of a wing with a steep rake, and a missile. On a streamliner like Vetter's that has a low, pointed nose, there will be lines of laminar flow which start at the point of the nose and move upward. And outward. One line will obviously flow straight up and over the top of the windshield. But if you were to go out and ride in the rain with talc powder on the front of the bike you would see that there are other lines just to the side of the nose point that start off straight up, but then begin to curve out toward the mirrors for example. They would also be invisible (other than the slight increase in skin area) to the steady head wind flow just as the straight up foiler is. But they might have more effect for any given amount of protrusion since they are closer to the area of max lift, there will be less time for the air to reattach. It would be more work to get them on just right so they are not in perpetual stall but the bike would look really high tech with two or three foilers.
