– 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

They can, but there’s already hot air available at the front of the car, so it’s cheaper to just use that. Running ductwork to the rear windshield is more expensive than running wires
