– Why can’t front windshields have the same defrosting method as rear windshields?

Question

The rear windshield defrosters seem so much more effective. Is it just the lines across the drivers field of view that makes it decidedly unsafe?

Answer 1

As others have stated, heated front windshields are fairly common in certain brands and market areas. You cannot use the same thicker heater filaments in front for visibility reasons. Front windshields utilize way thinner filament in more frequent pattern. Other type is a film type heated wondshield. There is a translucent heating film between the glass laminate. This type is less common but for example Mercedes and Volkswagen sometimes uses this method. Some cars also have the heating elements only under windshield wiper blades to keep them better in working order during winter.
