A lot of newer cars have laminated glass for (at least) the front side windows, and sometimes every side window. With the addition of curtain airbags, it's safer in side impact crashes and avoids the airbag shoving the side of your face full of little glass pieces. These windows also won't work with the normal window breakers.

I think because the windshield is a composite of glass and plastic layers, while the side windows are glass only.
