Privacy Lighting
Apple has a strong commitment to privacy. And according to one recent patent filed this week, that commitment is apparently also extending to the lighting systems within the Apple Car.
Specifically, Apple patented a system that would use car windows that have a controllable layer that could allow certain levels of types of light through while blocking others. The system, or the end-user, could control this layer at will.
This has a few interesting aspects. One application is the ability to illuminate the interior of a vehicle while using the controllable windows to block the light from exiting the windows. That may essentially mean that the driver and passengers could see inside the car, but no one else could.
