I do when im by myself once and a while. Last time i pulled up to a friends house at night i had the dash lights off and one of my friends asked how i could see how fast i was going so I showed him. He was like wow thats awesome! and then proceded to yell to everyone else standing by the fire that you could see the speed on my windshield which led to about 15 or so high schoolers hanging in my windows and trying to see it from the front. lol. Kids these days, i tell ya.
