Most of us would conclude that our windshield was a very useful piece of equipment. It keeps cold and heat; wind and rain; and untold numbers of bugs and other airborne road debris out of our faces.
The problem is that consumers have different and more limited expectations from the windshield than the automotive engineer. In other words, we worry about water leaks or ugly “dings” and cracks affecting our car’s value, while the engineer understands how such damage can affect the vehicle’s structural integrity and passenger safety.
