Teaching Cars to Read Our Emotions

It may be years before we’re all zipping around the roadways in driverless vehicles. But cars are already gaining some control over the behavior of their owners.

And a team of engineering students at the University of Waterloo in Ontario, Canada, has even developed technology to detect road rage and defuse drivers’ anger by playing soothing music.
