When a passenger gets into a ride-sharing car, he or she taps a mobile device that automatically opens an app interface that gives him or her control of the radio, climate and more. Eventually, any controllable feature, like the passenger seat and more, could be added. It works, because it uses open-source software to connect the rider’s phone to SYNC through the driver’s phone – without additional pairing. The software includes a translation feature, for when driver and rider don’t speak the same language. The rider simply types what he or she wants to say into the phone, and SYNC conveys it in the language of the driver.
