Tempered laminated exists. But I can't find anything about it being used in car windshields. My bad, sorry. The way I would do it would be chemical tempering b

  Yes, the break pattern of a windshield is consistent with annealed glass. If it were tempered, the entire window could become an opaque white whenever it was damaged by a rock and that just wouldn't be safe. Not that the 'spiderweb' pattern is easy to see through, but it's better than being fully opaque. I'm not familiar with any tempered laminates as we never made such, but a chemical process sounds more reasonable than trying to get laminated glass through a tempering furnace or laminate two tempered lites.
