I actually built a prototype for you idea. It used a styrofoam winglet and did work!old R90 guy"]Could you not just attach your plate with a hinge, so that at speed, airflow would make it horizontal, while at rest, gravity would return it to the vertical (thereby hiding your attempts at anonimity?)
I like that. A low tech tear off helmet cover. maybe a velcro attachment, and could be re-usable. Excellent!As far as helmets, I've seen a product advertised called Helmet Skins - making them tear-off shouldn't be too hard, (but maybe expensive - I don't recall what they cost)
But aren't the lame guys behind?The real solution is to ride with somebody else, and DON'T be the last guy in line - the cops, like all predators, pick only the weak amd the lame, and are usually satisfied after one "kill""
