Motorcycles are anything but aerodynamic. Today’s invention is a hinged windshield with a camera on board which helps smooth the airflow around a bike.
The camera forms an image of the rider’s helmet, on which is located a symbol. It can detect the position and distance of this symbol and thus operate a small motor in the windshield hinge. This allows the shield to follow closely and smoothly the movements of the rider as he sits up or crouches down or slides forward, whilst keeping a fixed distance from his visor.
A similar arrangement could be made for a vortex baffle behind the rider.
