Mercedes-Benz GL-Class: Infrared reflective windshield
The infrared reflecting glass prevents the vehicle interior from becoming too hot. It also blocks radio waves up into the gigahertz range.

These areas can best be seen from outside the vehicle by observing the light reflected off the windshield.
