Self-Driving Cars Won't Just Watch the World--They'll Watch You

It's Monday morning, you're late for work, and as you merge onto the freeway you see it: the sea of red brake lights. It's going to be a slow, frustrating trip--for all the suckers who have to drive their own cars. You click yours into autonomous mode and spend the slog getting ahead on work emails, or even catching up on sleep. Yes, the day you become a co-driver is fast approaching. But as cars master how to see, understand, and navigate the world, researchers are shifting their attention to another subject: you. Paradoxical it may seem, but the more control the car has, the more it needs to know about the person sitting behind the wheel--whether they're paying attention, their mood, even their health.
