Your argument would be far more compelling if someone could actually tell us why exactly the target market wants extra strong windows. I might not be the target market, but if someone says "Well I have a Ford and gravel flicks up and smashes my passenger side windows" I would be able to understand. The problem is that even the people doing the demonstration didn't actually tell us why you would want stronger windows.
