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.

In order to operate radio-controlled equipment, e.g. toll recording systems, areas 1 on the windshield are permeable to radio waves. In these areas, you can install radio-controlled systems.
These areas can best be seen from outside the vehicle by observing the light reflected off the windshield.
