I was on my way home from work today and I saw an old FJ40 driving with the windshield down. The temperature outside today in Fort Worth was 98 degrees. I started thinking to myself, he must have the windshield down to maximize the breeze so he could stay a liitle cooler. Then I started wondering what the original intent was to have fold down windshields on Jeeps. I figured it was likely a product of war and designed to make it easier to fire your rifle out of the front of the vehicle, but that is only a guess, or maybe it had multiple purposes. I'm sure there are some history experts on here that could confirm or inform me of what the designers original intent of the fold down windshield was. Maybe it was just to keep cool?
