We could soon stop driverless cars with a wave of our hand

A team of researchers has developed a system for driverless cars that lets pedestrians signal the car to either stop or continue driving with a wave of the hand. The system uses an LED display and sensors to detect a pedestrian nearby. The system could have an impact on the safety of driverless cars in cities where many pedestrians share the road with drivers. Once the car is aware of a pedestrian's presence, the pedestrian can raise their hand as a stop sign, which makes the figure on the LED screen turn green, stopping the car. The system, called Blink, was created by researchers at the Royal College of Art and Imperial College London.
