This could sound like a very stupid question, but I have to ask.
How does the RT windshield manage the water in the rain? I have felt the flow of air on the back side of the windshield and it seems that water would go up the inside of the windscreen while at speed in the rain. I am assuming it just runs up the inside and meets the flow from the front of the windscreen and goes up and away.
We get a whopping 2.5" of rain a year here, so it may be awhile before I would get to see the answer to my question.
But no worries......it's a dry heat.
