1 window down vs 2 windows down
going down the freeway at 65 mph with both winfows down in a crx. noticed stuff trying to fly around in the back. rolled up drivers window and left passenger window down, and stuff settled right down. has anyone done a comparison check on mpg . 1 window versus 2? I wonder if it is like a pickup bed, where the tailgate up gives better mpg due to the air pressure in the bed. had the vents on , but when my wife finally rolled up her window, that was when I started feeling air from the vents.
