Shepherd, a stupid idea just popped into my head... what if you were to use an ordinary DOT approved windshield BEHIND your custom aero windshield? Would the DOT be satisfied from a driver/passenger safety standpoint? Instead of calling the aero-piece a "windshield" you could call it a "deflector" instead? Just a thought... it might help you at least get a prototype rolling.

You could even have it hinged, like the visor on a bike helmet, so you could raise it and have them put their stickers on the DOT glass beneath.
