Re: eye-tracking
Well, the most obvious way of "working" while the driver is wearing sunglasses would be:
<sound alert>
Eye-tracking unable to confirm that driver is paying attention. Disabling all automatic features. Reverting to manual control.
<sound alert>
It's a safety system, so it should fail safe and fall back to the base level. Make the driver drive the car rather than play Candy Crush or watch movies.
