So far as I've seen windshields (the front glazing) on US autos have been exclusively laminated glass since at least the early 1940s. These usually will run a crack or two if you hit a hootie owl, but you generally will be able to see around the crack.

I think I vaguely recall a period of overlap when some European makers were using tempered glass for frontal glazing, which does craze and "frost the view" if broken. Local dealers for a time were claiming that "if you bought an import you'd have to replace the glass." The claim was totally false relative to the "US ready" imports they competed with, but there appeared to be just the grain of truth relative to some other "furrin" makers. I can't say that I've looked into this bit of history.

I can attest that when driving at 60 mph (~96 kph) when it's -10F (-23C) OAT, with the defroster (demister) blowing hard against the windshield in a 1961 Plymouth Valiant fully warmed up to sprint temperature, a broken heater hose on the aft side of the firewall produces an instant whiteout.

Great gobs of hot coolant are thrown in a spray against the windshield/windscreen, producing an impenetrable layer of ice instantly, hard enough that it can't be cracked with "anything within reach."

In addition, the instant transition to 100%+ relative humidity inside the car freezes the side glass to the rubber drip extrusions, effectively preventing one from opening a side glass to stick the head out the window. (I broke the crank handle.)

There was just time to verify that there was no tailgater close behind me before even the back glass went opaque.

It is called a "panic stop."

It then required both feet on the door to get it open, as the "humidity" (and maybe some splash) had penetrated the door mouldings and the door was also frozen - although not securely - shut. (Some of the rubber came off.)

Until the door was open, it was impossible to tell whether I'd cleared the road, although "the sound of gravel" (it did sound like music) indicated I should be clear.

That lesson took all of perhaps 37.3 seconds to learn - and will NOT BE FORGOTTEN. (And hopefully will NOT BE REPEATED.)

I don't think it mattered what kind of glass was in the windshield/windscreen.

The unexpected is always lurking nearby, especially when wheels are turning.
