– 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

I think Ford have a patent on it, so for other manufacturers to do it, they’d need to pay a licensing fee to Ford (**if** Ford wanted to let them – they don’t have to).

This is why it’s in Ford vehicles, but not others.
