Yes riding a motorcycle in a hurricane is frightening, so is driving a van. The advantage of a glider hull or any oval cross section fairing is that the lateral Cd is greatly reduced. This means the wind does not push the bike as much. The other factor in stability comes from down force which can be generated by the angle of attack. The shape can be shortened to 75% Kamm cut off as long as the center of mass stays well ahead of the center of pressure. We are fortunate here in that we have over a hundred years of aviation and motorcycle history including four national museums within a hour's ride. I test all my fairings in cross winds for minimal wind steer effects.
