It should have been called “ALLSHIELD”
The Windshield of your car has multiple functions, besides simply protecting you from dust, debris and the vagaries of weather. It also works as one of the safety features in the unlikely event of a collision, lending structural strength to the roof, not allowing it to cave in. In addition, contemporary windshields are made of laminated glass that doesn’t break in shards like conventional glass upon impact. This works as added protection for the occupants of the vehicle, preventing them from potentially severe injury.
