I may be wrong on this and other threads may have discussed this, but looking at the project Rushmore video it dawned on me that the fairing vent is designed to throw air not only around the driver but into him/her as well. I thought about my '12 and how much air I get and I couldn't understand why there needs to be more air. Then I thought about the Bluetooth/voice activated radio controls and what kind of helmet would be needed to make that system work IE 1/2, 3/4 or full-face helmet.
The way I see it, to use all the nice (and I mean nice) toys such as the voice activated controls and Bluetooth, you would need a quiet area around your mouth and ears. The only way to do that is with a full-face helmet. I ride a full-face helmet in the winter or when it is raining, but most of the time it is a 1/2 helmet. A full-face helmet can be very hot in the summer. Thus the fairing venting air in the face. Just a thought. Next question...how many H-D riders will buy a full-face helmet to utilize the toys?
