Soon, Your Car May Be Able to Read Your Expressions

When you shop for cat food online, Amazon knows who you are. When you look for the best airfares for summer vacation, Google knows who you are. Soon, when you get behind the wheel, your car may recognize you, too.

Using cameras with facial recognition software and other biometric indicators, automakers are looking to personalize the driving experience with cars that stare back at you, quietly adjusting seats and driving modes. They may even anticipate your wants and desires by playing your favorite music based on your mood. And it’s not only about convenience, but also about the possibility of improving safety and security.
