So, there's a camera in the dash looking up at the windshield and focusing where it expects to see a face, thereby using the windshield as a reflector? And maybe there's some additional etching and deposited films in the windshield to support the angles required?

And perhaps you can put cameras elsewhere, and similarly subtly modify the windshield or other glass to look at other things as well?
