PeliHellboy - pouring hot water on a frozen windshield will result in a hell of a lot of cracks, not just one. I was once pouring hot water down my sink and had a glass standing in the same sink. The glass wasn't even cold (let alone frozen) and the bottom cracked right off the rest of the glass from the hot water. I've also seen the bottom of test tubes get several cracks in them from being moved between something very hot and very cold too quickly.
