Odd, I have never seen that happen normally... On the other hand, that was an extremely hard impact in a rather flimsy car, so the supports gave way easily. Windshields can pop out, but only on some SPECIFIC cars (Usually cheap and flimsy ones), in rare circumstances, and usually under EXTREME force. (Also, I live in the United States (Although I have been to Europe) so I am more familiar with vehicular extraction of American vehicles, which usually are much larger, allowing for more crumple zone in the front end, making that extremely rare.) --- Post updated --- http://www.rodauthority.com/news/video-old-vs-new-car-crash-legit-or-altered/
The windshield being a part of the car is really unrealistic, If nobody agrees with the part that is said to be no popping out glass then theres only one thing to do. Make the windshield act like one, because right now its stupid
