Tempered safety glass. It breaks in long cracks instead of a zillion little
pieces. This is OK because the windshield is made from two layers of glass,
with a layer of mylar in between to hold the mess together when it breaks.
Side and rear windows are 'safety glass', which is the stuff that breaks
into a zillion little pieces, but have relatively rounded corners in the
breaks so that they are not as sharp.

OTOH, laminated safety glass, while abandoned years ago for automobiles,

What kind of glass do they use in windshields on the new cars?
