We trained for shooting through windshields at the Sheriff's Office here in Florida. Of course it is a last ditched effort to save yourself, but it works! You need to at least try and send all the rounds through the same hole in the windshield, but it can be done with accuracy. One of the instructors was easily able to hit steel targets at 15 meters consistently. If someone is approaching your vehicle and firing at you....shooting back through the windshield works!
