Good point. That piece of plastic is rather flimsy and may vibrate while going down the road. The dash panel is above that by about a foot. The ducting is the intake for the automotive climate system.
In our Axis we do have a good amount of wind noise that sounds like some is getting around the dash panel--something I hope I've already fixed with the fatmat sealing off the sides of the dash panel.
This has been a very interesting discussion.
